Still apple with never approve an app that allows storage and can play all formats like Perian. Heck I'd pay $30 for a pertain app on the new ATV via an app store.
All I am pointing out is that many people in the industry are reporting that it looks more likely than ever that Apple is planning to add ATV apps and an associated app store, which would be a great development. Of course Apple won't approve all app submissions, if they did it would kill the iTunes store.
Also, I am not saying that this purported app store makes the ATV better than Boxee. Neither product is out yet, and so we don't know what the final specs will be at launch, much less 1-2 years down the road. Anything is possible.
Both have their strengths and weaknesses, and I am excited about both.
