Firefox has a CPU usage issue and, consequently, can cause overheating problems in some laptops, particularly ultraportables. That's what I've found over the last couple of years.

But don't take my word for it. This is documented on a Mozilla support page entitled "Firefox consumes a lot of CPU resources." The page states: "At times, Firefox may require significant CPU [central processing unit] resources in order to download, process, and display Web content." And forum postings like this one about a Dell Netbook are not uncommon: "Mini9 would get way too hot."

The Mozilla support page goes on to say that "you can review and monitor CPU usage through specific tools" and describes ways to limit CPU usage, such as: "A Firefox add-on, called Flashblock, allows you to selectively enable and disable Flash content on Web sites."

Let me describe my experience. I find that tab for tab, Firefox uses decidedly more resources than other browsers--Safari, for example. And in the past (when I was actively using a Windows Vista-based machine) Firefox also compared unfavorably with Microsoft's Internet Explorer for CPU usage.

More specifically, here's the behavior as I see it. When I'm accessing sites with multimedia content such as the CNET front door, Firefox CPU usage will bounce around between 30 and 60 percent, and sometimes spike higher (80 percent and above), as indicated by the Mac OS 10.6.2 Activity Monitor.

On the other hand, the Safari CPU usage with the same pages open is much lower--typically between 2 percent and 10 percent.

My theory is that most users don't notice this because in mainstream laptops, this isn't an issue. But it can become an issue in ultraportables--typically under an inch thick--which are more sensitive to heat because of the design constraints. The ultrathin Apple MacBook Air, which I use as my main machine, is a good example.

The fan is usually an audible indicator of CPU usage issues. When I'm using Firefox and I have tabs open on multimedia-rich sites (which is par for the course these days), the Air's fan will almost invariably kick on and stay on until I close the tabs. As I write this, the fan has finally shut down after I closed the Firefox tabs (e.g, CNET front door). Those same tabs in Safari are still open and not causing any significant spike in CPU usage or fan activity.

When I contacted Mozilla, a technical support person guessed that Safari is possibly better at optimizing Flash-based sites compared to Firefox. And that may be true. However, I had similar issues before when I was using a Hewlett-Packard business ultraportable (also very thin like the Air) that were not necessarily tied to Flash usage. In short, Firefox was less efficient with CPU usage compared to Microsoft's IE 8. And the behavior was similar. The HP laptop would quickly heat up and the fan would kick on.

Finally, let me reemphasize that I'm guessing that most users don't notice this because heat dissipation is not a big issue for mainstream laptops that are not necessarily thermally-challenged when accessing multimedia-rich Web pages. That said, this has been a steady problem for me because I use ultraportables almost exclusively and has forced me to limit my use of Firefox.

ARM on Tuesday announced the launch an alliance of 35 tech companies to support development of Android-based products using its widely used chips.

ARM-based chips power the world's most popular smartphones, including--in the U.S.--the Apple iPhone, Blackberry Storm, Palm Pre, and Motorola Droid.

The Solution Center for Android alliance will serve as a resource for designers and developers of ARM technology-based products running on the Android operating system, which is the software on the popular Motorola Droid smartphone and Acer Liquid.

In addition to smartphones, Android powers digital picture frames and smartbooks--what the Windows-Intel camp prefers to call Netbooks. ARM-based smartbooks packing processors from Qualcomm, Freescale Semiconductor, and Texas Instruments should begin to emerge in force at the Consumer Electronics Show in January, where Lenovo, among others, will debut its first-ever smartbook design. The Lenovo smartbook is expected to be sold by AT&T.

"Developers require assurance that the components they are using are up to the task," ARM said in a statement. "Android was written for the ARM architecture and Android 2.0 was launched on high-performance (ARM) Cortex-A processor designs."

ARM says the launch of popular products is putting new pressure on the ecosystem that supports ARM. "As we have seen through the recent launches of handsets such as Motorola's Droid and Acer's Liquid, the Android platform represents a fundamental change in the open source ecosystem," Kevin Smith, VP of segment marketing at ARM, said in a statement.

Smith says that ARM now needs to ensure that development solutions are world-class. "ARM is in a position to foster an innovative ecosystem to ensure that device manufacturers have the best development solutions at their disposal," he said.

Analysts agree. "Consumer adoption of smartbooks, smartphones and other 'always on' connected devices is forecast to increase significantly in the next few years," Jeff Orr, a senior analyst at ABI Research, said in a statement provided by ARM. "Manufacturers of these devices need a support structure that enables them to develop cutting-edge devices quickly and affordably."

ARM said that in addition to the support of major device makers, silicon partners and solution providers, the Solution Center for Android comprises more than 35 members of the ARM community, including Texas Instruments, Mentor Graphics, and Archos.

Updated at 9:30 a.m. PST: Clarifying that "Netbook" is the name that the Windows-Intel camp gives to the small laptops and "smartbook" is the moniker applied by the ARM camp of device makers.

I'm going to break from the well-established tradition of comparing Netbooks to notebooks. This time my yardstick is going to be the smartphone. And no better yardstick than the Apple iPhone.

Verizon is selling Netbooks as kind of an upscale smartphone

This post updates a year-old piece (which, by the way, at least one writer took exception to).

As the holiday-shopping season approaches, many consumers face an ostensible choice between an inexpensive Netbook or more expensive notebook. I personally face that choice (or, at least, I thought I did).

Let me state up front that though I have used Netbooks on a temporary basis, I have never owned one.

I (now) believe that Netbook comparisons to mainstream laptops (which will always disappoint because Netbooks are slower, screens smaller, keyboards more cramped--and this list of comparative shortcomings is long) is really the wrong way to look at it. Let me illustrate.

I recently interviewed the chief technology officer for a large school district in Louisiana that had purchased a lot of Netbooks. And I asked what I thought was the most pertinent question: weren't performance and screen size a concern? She quickly pointed out that my perspective was all wrong.

In short, students in K through 12 are accustomed to iPhone-size screens and performance. So moving to a Netbook is a big step up. From this perspective, the screens are large, the keyboards expansive, and the performance more than adequate.

This suddenly made a lot of sense to me because of my personal experience. Take the iPhone 3GS (or Motorola Droid or BlackBerry Storm, take your pick ). To state the obvious, in many respects, this is a personal computer platform for e-mail, texting, Web surfing, music, navigation, YouTube, and the list goes on.

In other words, the iPhone is for consuming data and media as well as light production. Like the Netbook. But the Netbook, obviously, takes this to the next level. It adds a keyboard and a larger screen, which also makes it potentially a better production platform. So, it's an iPhone Plus, if you will.

And here's the real proof in the pudding. Where do you see Netbooks being sold these days (think Nokia Booklet)? At phone carriers, like Verizon. The last time I visited a Verizon store, it had 3G Netbooks prominently displayed right next to the Motorola Droid.

The point seems obvious to me now. Want to be more productive? Step up to a Netbook. And this follows the same logic of the CTO at the Louisiana school district. And upcoming tablets and media pads from Apple and others will also be marketed as a high-end iPhone-like device, in my opinion.

So, in the next month or so when I try to sort out which Netbook to buy (This CNET review says the HP Mini 5101 is one of the best Netbooks on the market now), I'll be shopping for an upscale smartphone not a stripped-down notebook.

NOTE: I'm not suggesting that anyone replace their iPhone with a Netbook. My point is that a Netbook can be used as an inexpensive adjunct to an iPhone or Droid for people who need to be more productive than an iPhone (or Droid) would allow.

Advanced Micro Devices discussed the Hemlock high-end graphics card due next week and third-generation ultra-thin laptop technology, among other topics, at the AMD Financial Analyst Day on Wednesday.

"Hemlock will get launched next week," said AMD Senior Vice President Rick Bergman, speaking Wednesday morning at the conference which was streamed live. "It's in production. You'll be able to buy it at e-tailers around the world. You can see there are two GPUs. Five Teraflops out of this baby," he said. (GPU stands for graphics processing unit. A teraflop is a trillion floating point operations per second, a key indicator of graphics performance.)

Hemlock is expected to be appear as an HD 5900 series product--what some reports have called the HD 5970.

Bergman also addressed AMD's third-generation "Nile" ultra-thin laptop platform. "Bring the real PC experience into the ultra-thin. Battery life well north of seven hours," Bergman said. This is due ... Read more

If the iPhone didn't finish off Windows Mobile in the smartphone market, the Motorola Droid may.

Windows Mobile is losing the last vestiges of its mojo--if it really had any to begin with--as the Droid and other phones based on the Android 2.0 operating system push the buzz meter needle into the red zone. Many in the media--which can play a big role in steering users to one technology platform or another--sense that Windows Mobile has now been relegated resolutely to has-been status.

Let's do a quick canvas of what some in the press are saying now that we're at the start of the Droid era. A post on SFGate.com (the Web site of the San Francisco Chronicle) is, like other commentary out there, clearly dismissive of Windows Mobile. "Curiously, Microsoft is nowhere to be seen in this battle royal," the author states, referring to the iPhone and Android.

And there's this more damning comment from a blog at SeattlePI.com. "Rarely mentioned, however, is another player in the mobile OS market--Microsoft. Why not? Because not many people in the smartphone world seem to really give a hoot about Windows Mobile anymore."

The litany of like articles is long. This post on PC World asks: "Has Microsoft Placed Its Last Mobile Bet?" The article cites research from Canalys showing Windows Mobile slipping from 13.9 percent of the worldwide smartphone market in 2002 to 9 percent in the second quarter of 2009.

The numbers are even less favorable in an accounting by ad service Admob, which compiles data on which operating systems are in use on mobile devices that access online ads. In August, according to AdMob, Windows Mobile had only a 4 percent share of the mobile OS market worldwide, down from 7 percent in February.

But getting back to my original premise of no mobile mojo for Windows. The fact is that consumers don't care about Windows on smartphones. In other words, while Windows seems to be a prerequisite for many consumers when buying a PC, it just doesn't come into play in a big way in a smartphone purchase.

This will have ramifications beyond Microsoft of course. Companies like Toshiba (and its attractive TG01 smartphone) will probably not be as successful on Windows Mobile as they would (will) be on Android 2.0. Or, at the very least, will not get the necessary buzz.

Then there's the Intel factor. Intel also wants to be a player, eventually, in the smartphone space. If it is indeed able to beat back Texas Instruments (whose chip is used in the Droid), Samsung (iPhone), Qualcomm (BlackBerry), and Marvell, it probably won't do it by sticking to the tried-and-true "WinTel" combination that's been so outrageously successful in the PC space.

And Intel is chasing a fast-moving target. TI, and all the other ARM-based chip suppliers cited above, are slated to bring out dual-core designs that can hit speeds as high as 2GHz (think next-generation tablets and media pads). In other words, they'll also be able claim the coveted speed mantle on phones, such as the Droid, where Windows Mobile is no where in sight.

So the Droid may not be the iPhone killer but rather the Windows Mobile slayer. Microsoft, of course, will always have the unassailable PC franchise. But, wait, isn't Android coming to Netbooks next year? Maybe the real battle royal for Microsoft is yet to come.

Chip supplier Marvell is hooking up with e-reader companies, hoping to take the lead in silicon design for this nascent market.

The market for e-readers, currently led by the Amazon Kindle and Sony Reader, is poised for growth, according to Weili Dai, a Marvell co-founder and general manager of the consumer and computing business unit. "The timing is right for the e-reader market to take off in volume," Dai said in an interview.

Marvell, though not a household name like Intel, is a major supplier of communications, storage, and wireless chips. Marvell, for example, supplied the Wi-Fi chip in the original iPhone and is a leading supplier of controller chips for solid-state drives.

In the e-reader market, Marvell is hoping to play a leading role in making e-readers a low-cost, mass-market device. "We're targeting a retail price of $150," Dai said. Partners include E Ink, a supplier of electronic paper displays; FirstPaper, an e-reading and advertising start-up; and Plastic Logic, an e-reader maker. Both E Ink and FirstPaper are backed by media company Hearst.

The Marvell Armada 166E system-on-a-chip, which will power a number of upcoming e-readers, integrates key features onto a single piece of silicon, such as the main processor--called an application processor--and the display controller. Armada is based on intellectual property from U.K.-based ARM, whose designs power most of the world's cell phones. Marvell ships 1 billion chips per year, two-thirds of which include Marvell processors running the ARM instruction set.

Marvell processors running at 1GHz will be used in many of the initial e-readers, though Marvell has designs that scale up in performance to 2GHz, according to Dai.

One of the first products to use the Marvell chip is the Entourage Edge, which claims to be the first "dualbook"--combining an E Ink EPD (electronic paper display) with an LCD and Netbook, notepad, and audio/video player functions.

Marvell will also power the dual-screen Alex e-reader from Spring Design. Like the Edge, Alex's dual-screen display design combines a monochrome electronic paper display with a color LCD screen.

"Periodicals are the next big frontier in eReading," Gil Fuchsberg, president of FirstPaper, said in a statement. To enable better newspaper and magazine reading experiences, e-reading devices will need richer layouts and more complex content, according to FirstPaper.

Corrected on November 3 at 7:40 a.m. PST: This story initially described FirstPaper incorrectly. It is an e-reading and advertising start-up.

By not coughing up a low-cost MacBook, as some had expected, Apple has ceded a potentially huge market to PC makers. But is this just all part of Apple's marketing genius?

$999 is as low as Apple will go.

The announcement Tuesday of the $999 white polycarbonate MacBook was pretty ho-hum as product refreshes go (same price, same color as before) but the implication was important: Apple is surrendering a large, emerging laptop market to Microsoft and its coterie of PC makers.

Not that it's necessarily a bad strategy. Market researcher Gartner said recently that Apple's shipments in the U.S. grew year-over-year by 6.8 percent to total 1.57 million during the third quarter, putting it right behind Hewlett-Packard, Dell, and Acer. Comparatively, overall PC shipments in the U.S. grew by 3.5 percent from a year earlier.

But among those unimpressive overall PC numbers (HP's third-quarter shipments grew only 2.7 percent), was an impressive statistic for Acer: buoyed by Netbooks, Acer's shipments grew by 61.4 percent year-over-year, and it blew past Dell to become the No. 2 PC maker worldwide based on this growth.

Granted, Netbooks are a relatively low-profit segment (i.e., profit on a $400 Netbook is going to be a lot less than that on a $999 laptop). Nevertheless, they're a hot market. Intel CEO Paul Otellini has stated numerous times that Intel was able to create a market that grew faster than either the iPhone or Nintendo Wii. Case in point: Windows 7-based Acer Netbooks are now big on the Home Shopping Network--which claims to have sold more than 5,000 in one segment on Saturday.

And that's not the only market Apple is punting on. A new category of inexpensive, thin laptops has emerged with the roll-out of Windows 7 on Thursday. Like Netbooks, these laptops are light (typically 4 pounds) and don't include an optical drive. But they are relatively powerful and full featured. The 15.6-inch Acer Aspire Timeline, for example, with a 320GB hard disk drive and dual-core Intel processor is fairly well-endowed at only $500.

Windows 7 has spawned a new breed of inexpensive laptops at retailers like Best Buy and Frys.

At many stores on Thursday, Best Buy refreshed almost its entire stock of laptops: all running Windows 7 and all sporting new model numbers. Frys--a megastore electronics retailer with locations throughout California, Arizona, and Texas--also refreshed many of its laptops with new Windows 7 models.

One of the most inexpensive Windows 7 arrivals is the Gateway model EC1410U. This tiny laptop is distinctly Netbook-like in appearance but uses a more powerful Celeron M ULV 743 processor (1.3GHz, 1MB cache) than the Atom-chip fare found in Netbooks. In addition to the Windows 7 Home Premium Edition 64-bit version, other features include 2GB of memory and a 250GB hard disk drive.

Many seductive Windows 7 newcomers are categorized as "ultrathins." These slim designs are typically discernibly bigger than Netbooks (though, as evidenced by the Gateway above, it's now always clear-cut) and pack more processor horsepower. The Toshiba Satellite T-135 (model: T135-S1309), which falls into this category, is priced at $549 at Best Buy and comes with Windows 7 Home Premium Edition 32-bit operating system, a 13.3-inch display, a dual-core power-efficient Pentium processor, 3GB of memory, a 320GB hard disk drive (5400RPM), and built-in Web cam.

Dell, Acer, Intel, and others together are, in effect, creating a muddle of light laptop categories as part of a not-so-well-orchestrated marketing strategy, according to an analyst. This is expected to become particularly acute when a deluge of new Windows 7 laptops hit the market this week.

Acer offered a graphic example of this recently when it introduced a small, inexpensive Windows 7 notebook--the Aspire Timeline AS1810T--that, from all outward appearances, looks like a Netbook. But it isn't--at least as defined by Intel. It's a new category of laptop called an ultrathin.

"There's a lot of confusion that Intel has created and they haven't really segmented the market that well," according to Bob O'Donnell, an IDC Research vice president.

And it gets more complicated. The inexpensive ultrathin is, in turn, competing now with the expensive luxury laptops, like the Dell Adamo, according to O'Donnell. "Ironically, what's actually happening we think is that the (ultrathin) is actually killing the high-end ultraportable," O'Donnell said.

Here's the problem: any given Windows 7 laptop with an 11.6- or 12-inch screen could be a Netbook, an ultrathin, or a high-end ultraportable, each with distinctly different price-performance characteristics not readily apparent to consumers.

"There's too many overlapping products," according to O'Donnell. Intel tried to prevent this from happening by declaring that any laptop with a screen larger than 10 inches diagonally is not a Netbook. That policy is fine in theory but does not carry over to the real world of head-butting competition among PC makers where even the subtlest production differentiation can mean a leg up on the competition.

Intel says look at performance and price. "Which offers the best performance overall? That's important," said Intel spokesman Bill Calder. "Pricing is a factor too. While some ultrathin laptops including 11.6 and higher are very affordable, none are in the $249 to $399 range that typically defines a Netbook," Calder said.

Some consumers might say it's not a big deal. But ... Read more
