Netflix in 1080p using Apple TV is stellar compared to watching Netflix using the wii.
The photo stream and access to my iTunes library of music and video on my tv is awesome. This little $99 device ties it all together. iPhones with iPads with flat screen plasma. It's just way too easy.
The little controller takes some getting used to. Once you start inputting your username and password the first time, and make some errors, you will understand what I mean.
Everyone in the family digs the picture quality. There is a big difference.
Get one if you use an iPad or iPhone. It just makes sense.
