I'd really appreciate any opinions on this. i'd like to get the ATV but want to know what to expect. I hope that a FW 400 HD would be ok for streaming all content (as music is seamless with just the airport express), but it would even more sweet if i could just get an new AE and set up an external media library to stream over Airdisk. so, is Airdisk and it's USB interface limitations still enough for the ATV? would be watching high quality DVD rips and lossless music files mostly.
