I got an iMac yesterday. Frontrow popped up and it looks very similar to AppleTV interface. I am purchasing a long dvi to hdmi cable and audio cables to hook up to a 42" Bravia (Sony). I plan to watch Hulu on the tv via the iMac. What can't Frontrow/iMac do that AppleTV can do? Suppose if AppleTV has become obsolete here in my bedroom, I'll move it to another room.
