Android is a decent gaming platform, but last I knew a lot of the AAA games on there still don't have controller support. Smart to leave the Play Store and Tegrazone intact. the OUYA model just wasn't going to work.
The hardware is fine as it will play anything out there right now pretty easy.
This is the first one of these consoles that I actually like, except I think the price might be $50 too high. Full Play Store access means it makes a great streaming device for home theaters.
