i dont think you are the target audience for the atv.... to me the atv is meant to supplement the apple ecosystem. so if you were firmly entrenched in itunes then the atv makes sense. It can do basically everything you listed when you replace plex/amazon for itunes. i have 3 atvs as well and i use them daily.

kind agree on this...however id do one more...apple needs an itunes server...there needs to be 4 airports:
express extreme time capsule itunes server
your airport is ALWAYS on so why not have it serve itunes content
thsi doesnt completely bother me as my mac mini is always on and everyday im either adding a new show or movie or music to itunes...but a stand alone itunes server would be great for less techy folks
I guess I would agree, I've always tended no matter what device I use to support the Ecosystem that is available on the largest number of Devices, so Amazon for Books, streaming movies, Vudu for HD Movies, I don't want to be locked into one companies ecosystem
