I really like the new ATV; however, I'm probably the target "normal" consumer for it. I don't have any gaming systems (xBox, Wii, etc.), my HDTV is only 720, and I have a basic stereo set up, which is plugged directly into my TV (no surround sound). The ATV is pretty much exactly what I want, which is to stream Netflix, plus video, music, and pictures from my MBP, without a lot of hassle. For this price, I'll definitely be buying one.
I have to say I don't get the new Nano at all. I guess it's for someone who wants something tiny like the shuffle, but with a bit more functionality. I have last year's Nano, and just bought an iPhone, so fortunately I'm not in the market for an iPod of any kind. However, I'd definitely take the Touch over the Nano, even at the additional cost. Maybe that's what Apple had in mind. 😀
