This is pretty cool, I guess. I don't get exactly what it is.

The Microsoft handheld is not a portable gaming system, but it is capable of playing games. It is most likely that the Halo image on the screen has been superimposed and is not a screenshot of actual gameplay.

The device is more like a mobile, handheld PC than anything else, I mean, it's freakin' huge. What on earth would you expect Gamers to do with that thing.

Oh, and the image you see on is just a prototype, the final product will be different than that, hopefully significantly smaller.

Expect the official announcement on March 2nd. Xbox Space will let you know what's going on as more details become available. If you can't tell by this post, I have no idea what's going on, but I'll do some digging and get back. Sorry.
