The ability to run Android apps would be the key. Plus, for an HTPC, Android (tablet UI or Google TV, take your pick) has a much better interface than XBMC, IMO.
Part of why I use XBMC is because it will play almost anything you throw at it. Sticking it on extremely resource constrained hardware gets rid of that feature.
Waiting with baited breath for mine to turn up! :-)
However, it was very naive of the grandparent poster to think that slow CPU powered menu screens means that the hardware accelerated video is lacking.
No, it doesn't play my 13GB copy of Tron, but it plays every single 720p MKV I've thrown at it.
