With all the action going down at Google I/0 you can be excused for missing this latest tidbit: the folks behind Wikitude have made the beta version of Drive (their augmented reality personal navigation app) available for free for 2,000 users. And we just got our hands on it, so we know that there are at least a few downloads left at the Android Market. The full-featured demo sports NAVTEQ map data, both AR street view and 3D map view, worldwide coverage, voice commands, and both driving and walking directions. There's no word yet on when the final version will be released, so this might be your last chance for a while to play with what's stacking up to look like a pretty decent application.
