Is it worth getting ATV3 or just go with the 2?
Well new you can only buy the 3, but at 1080i, the 2 would be fine.
You have to take into consideration that if Apple were to release a major update with let's say Apps or something like in the future, realistically the 3 will be the only one to get that update.
Plenty places still have atv2's for sale
I have a 32inch samsung. My friend is giving me his atv2 for only $50 i just hope it dosnt bother me that its only 720p but for that price why not right?
