Twelve months ago NVIDIA stood on stage at CES and introduced its Tegra 2 SoC. It promised dozens of design wins and smartphones shipping before Spring 2010. That obviously did not happen.

What instead happened was NVIDIA lost a number of design wins, many of which we centered around mobile OSes other than Android. There were a number of Windows Mobile/Windows CE based designs that never made it to market, and a lot of efforts around earlier versions of Android that never went anywhere.

In the time since NVIDIA’s CES 2010 announcement, the company has shifted resources and focused its entire Tegra team on a single OS: Android. Choosing Android isn’t a hard decision to understand, of all of the available smartphone OS options it has the most momentum behind it.

We've been playing around with two OMAP 3430 based phones for a while now - the Nokia N900 and Motorola Droid. Though they aren't the newest smartphones to come across our bench, both are important baselines and still very relevant devices, each for totally different reasons: The Motorola Droid is the phone that launched Android into maturity with 2.0. The N900 is Nokia's latest internet tablet turned smartphone running Maemo - which will evolve into MeeGo through joint Intel-Nokia collaboration and run atop Intel's Moorestown platform.

These are two phones that were both all the rage before their release, and we're visiting them now, a little over midway through their life cycles, to see how they're doing and how they compare against everything else we've reviewed.
