If you have a mac, iphone, ipod, or ipad Airplay is a great AppleTV feature. If you're not an apple household there's little reason to go with one over a new Roku (so I've read) ...You could always get all nerdy and make a Media centre computer with a Linux box and XBMC... My problem was more sending my signal to a non-apple device that uses DLNA instead of UPnP. I downloaded XMBC media centre, a free app, and it worked just fine after a trip to the settings menu. Not sure if you can get it for iPhone but there must be some other fix for that one. If you're into the iTunes/Apple thing then the AppleTV is probably the way to go.
