I'm getting ready to pull the trigger on an ATV either version 3 or 4. I've been reading the forum and it seems the 4 might be overkill for what I want to do. I have a small office (8 ft by 9 ft) and I've mounted a tv with a shelf below it. I've also mounted a pair of speakers on the wall. If I go for the 3 I plan on ditching my audio receiver and picking up this amp which will allow me to stack the 3 on top of it saving me precious space. I don't plan on doing much more than listening to my music and a movie every now and then. I checked the 4 out at my local Staples and it really seemed to me overpriced for what my needs are. Is apple going to continue selling the 3 and supporting it? Are there former 3 users in my situation that moved to a 4 and what benefits are there? Any help is appreciated.
