My AppleTV finally arrived yesterday. Wow! It’s so simple to use and setup. I sync’d over all my music, and videos from the MacBook Pro. This uses about half of it’s capacity. However, I also have an old ‘lampy’ iMac. Given that it has a basic Airport card I was worried it wouldn’t be able to stream video. But sure enough it does, obviously it’s a little slow to start but it works really well!
