This week we met Motorola's Droid, the first handset with Android 2.0. To an outsider, it just looks like another Google smartphone, but 2.0 is more than that: it's proof that Android is finally going to take over the world. So Wait, What Is Android, Exactly? In Google's words, it's "the first truly open and comprehensive platform for mobile devices." That doesn't mean much, so here's a breakdown: It's a Linux-based, open-source mobile OS, complete with a custom window manager, modified Linux 2.6 kernel, WebKit-based browser and built-in camera, calendar, messaging, dialer, calculator, media player and album apps. If that sounds a little sparse, that's because it is: Android on its own doesn't amount to a whole lot; in fact, a phone with plain vanilla Android wouldn't feel like a smartphone at all. Thankfully, these phones don't exist. - Steve Woda
