I don't really use apple gadgets, but I can see the potential in these collaboration. I guess the impact is bound to be bigger on TVs, maybe having a PSN system on the iPhone where you can download games and stuff would work well, altough SONY has the xPeria as a gaming phone already but it can't compare to a iPhone/PSVita hybrid
Apple is doing way too good to even join forces with anyone.
I would rather see them making a console system, because if they did it right, I'm sure it would be a hit.
Apple Inc. has more cash then the U.S. gov't (says a lot, doesn't it).
Sony is already making GoogleTV, both as a standalone unit and built into certain TV models. So it would be unlikely that Apple would choose them for Apple TV.
Hopefully Apple will make add-on version of Apple TV, so that people that don't want to by a new display can enjoy the product too..
