A small brouhaha is erupting over Windows 7 and Intel processors. The hubbub is centered on which Intel processors will not support "XP mode" in Windows 7 and, by extension, which PCs will not support XP mode. Retail laptops may be one of the most prominent segments affected.

What is XP Mode? Here's how Ina Fried of CNET News describes it: "XP mode consists of two things, the Windows Virtual PC engine and a licensed copy of Windows XP Service Pack 3 as a packaged virtual machine. Although neither piece will be included in the Windows 7 box, XP Mode will be a free download for those who have a license to Windows 7 Professional, Windows 7 Enterprise, or Windows 7 Ultimate."

XP Mode (XPM) is aimed at businesses that have Windows XP-specific applications that they need to run on Windows 7. XPM allows XP applications to run seamlessly on Windows 7, according to Microsoft. The catch: Intel processors must have Virtualization Technology, or "Intel VT," in order to run XPM. (I won't cover Advanced Micro Devices processors here but will address AMD in a later post.)

Ed Bott's Microsoft Report says that "some of the most popular PCs on the market today...won't be able to use the vaunted Windows XP mode in Windows 7."

Bott lists Intel desktop and mobile processors that will and will not support XP Mode here and here, respectively.

Intel mobile processors may be the most problematic in supporting XP mode; not because of the raw numbers--most newer Intel mobile processors do, in fact, support Intel Virtualization Technology--but because a disproportionate number of those that do not have VT (and therefore don't support XP mode) are laptops sold at retail. (And, undoubtedly, some small businesses purchase laptops at retail.)

In the Core 2 mobile camp, the P7350/7450, the T5200/5250/5270/5300/5450/5470 series, and the T6400/6570 do not support VT, according to Bott's blog. And this can be confirmed on Intel's Web site.

A quick glance at Best Buy shows a somewhat lengthy list of laptop SKUs (models) with, for instance, the T6400 (non-VT) processor. The list includes Dell Studio, Toshiba Satellite, HP Pavilion, Sony Vaio, Asus, and Gateway laptops.

In the $600 to $899 laptop range, I found about 30 different SKUs with T6400 processors, though it should be noted that some of these SKUs are simply models with slightly different configurations.

And a quick search on CNET Shopper turns up a number of consumer models with the T5270. The point? To state the obvious, consumers will have to verify which processor their laptop has.

In an Intel blog, Nick Knupffer asserts this won't be a big issue. "Having VT on these consumer laptops is not going to be an issue--because the consumer versions of Windows 7 (Starter, Home Basic, and Home Premium) do not include Windows XP Mode," he writes.

And Intel, in a statement, had this to say. "Intel introduced its Virtualization Technology in 2005 and has shipped over 100 Million chips with the feature. Windows XP Mode is targeted for business customers. It is available on the mid to higher end versions of Windows 7 and is supported in hardware by many Intel processors."

Intel continued: "Intel vPro technology PCs are required to have an Intel VT capable CPU and Intel VT capable BIOS. They are the best platforms for testing and deploying Microsoft Windows Virtual PC and Windows XP Mode."

Some laptops, especially ultraportables, brazenly push the envelope on pricing. In the age of the ultra-cheap Netbook, are they really worth the $2,000 to $3,000 price tag? I've listed three egregious offenders and two that fall into the less-scandalous-but-still-snooty pricing category.

Let's start with the Hewlett-Packard Voodoo Envy 133, probably the most brazenly overpriced of the batch because it will still set you back as much as $2,700 despite the fact that it hasn't been updated in almost eight months and, accordingly, comes with obsolete hardware.

The 13-inch ultra-slim Voodoo Envy 133 model NV4050NA is priced at $2,699.99 (with "instant rebate"), but the buyer gets nothing extraordinary for this extraordinary price, with the possible exception of an external optical drive and a power adapter with a wireless access point built in.

The stratospheric-price-defying negatives include an old processor, a lagging-edge solid-state drive (64GB instead of the current 128GB standard), and last year's graphics.

Here's a quick rundown:

• An old Intel Core 2 Duo SP7700 Processor (1.8GHz) processor (think: original MacBook Air)
  
• A passé 64GB solid-state drive
  
• An ancient Intel graphics media accelerator X3100 (think: original ThinkPad X300)
  
• A short-lasting 3-cell battery
  
• An external optical drive (this is one of the few pluses)
  

The next criminally overpriced laptop is the 13-inch Sony Vaio Z Series ultraportable laptop (3.4 pounds). The VGN-Z590UBB model is priced at $3,899.99. Amazingly, this comes with only a one-year warranty.

But first a few positives. One of the most unusual features of the Vaio Z is a discrete Nvidia GeForce 9300M graphics chip. Almost all of the newer ultraportables come with Intel 4500MHD integrated graphics only. So this is certainly a plus and echoes the Nvidia 9400M graphics in the newest MacBook Air. It also packs DDR3 SDRAM memory. This is good too.

But there is little to justify (in my opinion) a price tag approaching $4,000 (unless Sony has doubled up on gold memory connectors and isn't telling us about it). Yes, you get new Intel silicon (a P9500 running at 2.53GHz), hybrid graphics (Nvidia and Intel), a high-resolution LED display (1600 x 900), but nothing that justifies forking over $3,900, even if you're Merrill Lynch flush with stimulus-package cash.

The third up is the 12-inch Fujitsu LifeBook B6230 (3.2 pounds), priced at $1,799. Though it's listed lower than the Voodoo and the Sony, the features are strikingly unimpressive for the $1,800 list price. An archaic Intel ULV U7600 (1.2 GHz) processor (533 MHz front-side bus), 1GB of memory, an 80GB hard disk drive, 802.11a/b/g wireless (no "n" here), and a one-year warranty round out (yawn) the features.

In descending order of extravagance, at No. 4 is the 12-inch Toshiba Portege R600 model S4202. Price aside, a quick glance at the features would impress most prospective buyers: very light at 2.4 pounds, standard 3GB of memory, a 128GB solid-state drive, a integrated optical drive, 802.11a/g/n wireless, and a Webcam.

What's the downside to these decent features? You guessed it, the price: $2,999--and that includes a slow Intel SU9400 (1.4GHz) processor. With full-featured Netbooks costing about one-sixth the price (between $500 and $700) and an HP Pavilion dv2 ultraportable on the way priced at about $900, the Toshiba begins to look, well, overpriced.

Finally, I must mention the Apple MacBook Air (I know I'll get slammed for this). The newest version with the upgraded Intel processor, Nvidia graphics, and a 128GB solid-state drive is certainly a vast improvement over the original. But in the age of the Netbook and seriously budget-constrained buyers $2,500 ($2,499) is just too expensive.

Apple needs to bring the high-end MBA down to about $2,000. Still pricey but probably justifiable (to the lucky few out there who sold their Nantucket vacation home before the crash).

Note: This is not a CNET review. This reflects the opinion of Nanotech: The Circuits blog only.

Intel will bring out a new Core-architecture processor for lower-cost ultra-thin laptops later this year, according to Intel sources at the Consumer Electronics Show in Las Vegas.

The processors will distinguish themselves by targeting a price segment below pricey ultra-portables, which typically start at around $1,500 and range all the way up to $3,000--and higher in some cases. The processors will not compete with the Atom processor that powers Netbooks, which usually top out at $500.

In this sense, the new chips will be comparable to Advanced Micro Devices' recently announced Athlon Neo processor for ultra-thin laptops priced between $700 and $900.

The processor is "going to enable notebooks that are less than one inch (25mm)," according to the sources. The architecture will be a "tweak" of Intel's existing ULV (Ultra-Low-Voltage) processors, said the sources.

Current ULV Core 2 Duo mobile processors, such as the SU9300 and SU9400, have a power envelope (Thermal Design Power or TDP) of 10 watts, much lower than standard Intel mobile Core 2 Duo processors that have a TDP of between 25W and 35W.

ULV processors are used, for example, in ultraportables such as the Toshiba Portege R600 and Sony Vaio TT. Both are ultrathin high-priced boutique ultra-portables, starting at about $2,000.

Intel also offers SL series low-power mobile Core processors with a TDP of 17 watts.

The package size of the new processors will be 22 millimeters by 22 millimeters, according to the sources.
