So, I never had much interest in AppleTV before, but with the new release for only $99, I started checking it out, and I was thinking, if I bought an AppleTV, first I could stream video from my mac mini to my tv wirelessly, right? Second, if I could purchase a tv input for my mac, I could record my shows without the DVR from my cable company and, again, I could stream wirelessly to my tv, right? Also, all I'd have to do to watch the shows on my computer in the bedroom is take the AppleTV to the bedroom and watch them wirelessly, right? (Or, eventually, I can buy a second AppleTV for the bedroom) Thus, for a reasonable upfront investment, I can ditch two of the DVR boxes that I pay a monthly fee to the cable company? Am I missing anything?
