I'm having a similar dilemma. I'm leaning towards the 64gig but I'm not sure what I would fill it with. Another user said app size limit is 200 megs and most apps unless a game won't be near that size. So this leaves me with tons of free space not knowing what can be stored on it.
Apple never came out and said we can use the storage for video, music or pictures like how it was on the first Apple TV. So I'm stuck wondering if we can. I don't want to get the 64 gig and it ends up being only for apps, screen savers and the OS.
I want to know if we can actually store multimedia on it. Does anyone have this confirmation? Or someone who has a dev kit can confirm?
I've not seen anything confirming it yet. I personally think it will be apps, music, videos which I wouldn't store on there, only apps to be honest.
