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.

Though the Motorola Droid and Apple iPhone have different chassis, their high-octane engines are similar.

The internal similarities begin with performance: both devices are fast. The iPhone 3GS is already distinguished for its speed. And the Droid is quickly garnering similar accolades.

"The Droid makes a big leap in internal performance. Compared with its rather sluggish Android predecessors," CNET Reviews said, citing the speed at which the Droid opens applications and menus and scrolls through lists and switches display screens.

"We're really pumped to see all the industry excitement it's created," said Jeff Dougan, the OMAP 3 product marketing manager at Texas Instruments, which supplies the OMAP 3430 processor that powers the Droid. "This is the first handset that truly realizes the full potential of Android," he said, referring to Google's Android 2.0 operating system that runs on the Droid phone.

The TI processor, like the one in the iPhone, is based on an a new architecture called Cortex-A8 from U.K.-based chip design house ARM, whose wide variety of chips populate most of the world's cell phones. Dougan says most smartphones currently on the market use an older, lower-performance ARM architecture than the Cortex-A8--with the exception of the Palm Pre, which opted for the newer TI chip. The Cortex-A8 provides a "two to three times performance boost" over older architectures, according to Dougan.

Max Baron, an analyst at Microprocessor Report, says the chips in the Droid and the iPhone (see not below) are so alike that differences are more dependent on the operating systems the two chips use and how successfully each phone maker optimizes the OS. "With chips that have near-similar specs, the optimum OS and the look-and-feel of the user interface may make or break the product," Baron said.

"The caveat, however, is that even small differences in chips will surface and become important differentiators as soon as the market forces you to increase the screen size or add more pixels per screen, or execute more power-consuming applications," he added.

The raw MHz ratings on the chips are slightly different. The processor in the iPhone 3GS--which is believed to be based on the Samsung S5PC100 processor--runs at 600MHz, according to most accounts. The Motorola Droid's TI chip is rated at 550MHz though theoretically it can be run as fast as 600MHz, according to TI's Dougan.

Both phones also use PowerVR graphics from Imagination Technologies--a company that both Apple and Intel have invested in, testifying to how hot its ultramobile graphics technology is. The PowerVR SGX is renowned for its ability to process several million triangles-per-second--a key indicator of graphics chip performance--blowing away other phones and the previous version of the iPhone.

Other internal specifications are similar between the two phones, including memory capacity (either 16GB or 32GB) and communications chips that offer 3G, Wi-Fi, and Bluetooth connections.

So, internally the Droid is every bit the iPhone's equal. And future versions of TI OMAP 3 chips that may appear in upcoming Droids will be backed by formidable ecosystems, according to Baron. "Investments in application software may lean more toward the TI components," said Baron, given TI's strong support of the entire chip ecosystem, including auxiliary chips and software development tools.

Note:: Apple's and Samsung's reluctance to release information about the processor used in the iPhone 3GS has made it difficult to determine if the chip is based on the Samsung S5PC100, according to the Microprocessor Report's Baron. Many iPhone 3GS reviews and teardowns, however, state explicitly that the iPhone's processor is essentially the Samsung S5PC100 processor.
