Here's what I've been able to sort out so far:
Re: reports that the apps could spam your credit card and force purchases without confirmation (such as on SomethingAwful)
From everything I've seen this is false. When the purchase request goes through, a confirmation screen is shown by the OS. I've talked to others about it, I've seen it myself on the dev kit, and I've seen others purchase on video.
The bad news is, there's a few glitches in purchase process currently that are bad, but fixable by launch.
1. Occasionally (based on if a game with a certain debug flag set), when the confirm screen comes up to purchase, it may not properly display the cost of the game. I've never seen it, but in the Verge review video at 5'40" you can see it happening to them. The text is red, but sometimes the box background is red as well (so it's red-on-red and they can't read the price). Again, never seen it, but this clearly sucks.
2. The default is 'purchase' instead of 'cancel' when you bring up the confirm screen. You could easily, accidentally hit this and buy something when you didn't mean to. We've complained on the forums recently about this, hoping it's fixed soon.
Re: Input lag is terrible
I've been playing a lot of games on the store and this one is weird. Some games have terrible lag and some do not. I don't have a time measurement yet on the built-in lag from the wireless controllers, but seeing that some games are very responsive, it seems like it's
possible to get good times.
The biggest culprit that I've seen acknowledged by lots of devs now is that it's the Unity plug-in for controllers causing lag. You don't have to use Unity but a lot of games do. And I can confirm that for the several Unity based games I've tried, they all had some nasty lag. Like "press the stick right quickly take your hands off the controller then watch your character move" sort of lag.
Good news: Unity dev team has been present on the ouya forums recently and have already issued a patch that supposedly fixes the terrible lag. I don't use Unity (we're using Java), thus can't confirm yet the Unity fix. It will effect a lot of games--but it seems like the fix is there. It just has to be brought back in by devs. Going forward though, they should better off.
That's what I've seen currently, but I'll be keeping an eye on things as (such as the store and controller responsiveness).
Full disclosure--we're
making a game for this thing and it sucks that the console is fairly poopy right now. I've pushed on the ouya team on the forums because I'd very much like it to be cool and fun. They have been fairly responsive so at least they're reading things. We'll see how that turns out at launch though.
