Come on, come on, come out already! Since this is the launch week for the Verizon/Motorola/Google Android Droid X and Apple's iPhone 4, Microsoft trotted out a prototype Samsung phone running Windows Phone 7 last night to show folks that they're still in the smartphone game.

The Samsung phone isn't a final WP7 device; it looked to us like the latest build of WP7 hacked onto a European Omnia phone. But the software ran fast and smooth, with all the features we've come to expect from Windows Phone 7: big, bold text, Xbox Live, Zune, Bing and such.

Windows Phone 7's biggest problem is that it just isn't here yet. During the Summer of the Smartphone, Microsoft is still simmering their stew. This isn't a surprise: when they announced WP7 back in February, they only promised it around some vague "holidays" in 2010 - and that could be New Year's Eve.

But with Android and Apple ramping up their lineups, will there be room for Windows Phone 7 in six months? Tell us what you think in the comments, and check out the latest build of Windows Phone 7 in the slideshow below.
