A store near me is selling Apple TV really cheap atm and am considering getting one but am on the fence. The main reason for my uncertainty is that my TV is the same size as my iMac so would there really be any point doing on my TV what I can already do on my Mac? Does it do anything the Mac doesn't? I could connect it to the family lounge room TV which is bigger butbi don't see why they would want to stream my music and movies as they have different tastes. So try and talk me into buying one. What will I get out if owning an Apple TV?
