See, this statement I have no problem with. Saying the market is too small to sustain the console is completely different from saying the market is nonexistent, as it seemed like you were implying earlier. I honestly doubt the Ouya will go anywhere in the mainstream market, but even if the company folds immediately after launch, there will still be Android developers hacking away at it to make sure they get their money's worth. If you browse through Android forums, some of the most obscure devices have custom ROMs.
Obviously the key word here is "AFTER" launch...
While I'm not as 100% confident as Newt that this thing will never ever materialize, he is right that there is no significant benefit to pledging $100 right now over just getting it when it comes out.
As I mentioned, right now I'm pledging $140 for the Kickstarter-only brown Ouya, but I'm trying to decide if even that's worth the risk. Gonna have to admit I'm kinda leaning towards no.
