From a gaming perspective, if we could get a bluetooth mouse working (have we?) with an easy-to-toggle pointer I'd love to see some of the linux games out there get ported (Quake 3 would be particularly cool).

If we provide the means for developers to port 3d games with a minimum of hassle, we will get 3d games. It shouldn't be marketed as a gaming device, though, as that will just set it up for failure.
