I bought the Blue Ray and PS3 devices for their wireless capability to communicate with the laptops primarily because I use my computers as my media source. Such as videos and pictures we take on trips etc. I'm not much into movies but my wife is. She usually downloads them or buys pay to view from our satellite service provider.
I got the Apple TV and the iMac for wireless digital slide show and music. I can queue up a show very quickly on the flat screen TV. I love it, I can do the Ken Burns slide show effects with music. It sure beats the the olden days of using Kodak carousel slide tray, projector, retractable white screen, and darkened room.
