The problem I see with android gaming devices (this and the ooya) is that the hard ware keeps increasing on each new release so your games are going to require more and more power.
Where as a platform like the PS2/3, Xbox*, DS or whatever has a very fixed hardware setup and it doesn't change. So a game made at the release of the console/handheld will work on a model made at release or 3 years later and a game made 3 years later should work on a unit from launch or current (there are some times this is not the case, but it is an exception not the rule).
I would love to see ooya and this take off and allow for more indie development. But I see stuff becoming too outdated too quickly.
