I am much more interested in the new windows phone, a fairly powerful system, with all the functionality of the Zune, and a smart phone all rolled into one sweet little package.
Then again I don't think of touch screen devices as true games platforms unless they have buttons. You can't beat a good analog control, shoulder buttons, and couple of other buttons as well so that you are not left tapping around blindly cause your oversized man fingers are covering up half the screen, let alone detection issues, which you pretty much never have with a button unless you have worn it out.
