Just bought the my book live 2TB last night(good deal at a local store for $140). Hook it up to airport extreme, its up and running just fine. Its fast enough to stream 720p movie to my MBA 13". I was pretty happy for the performance. Its a very simple fast NAS for home you can buy right now. No problem with lion after I did firmware update. Just wondering any of you guys here are using the same setup? any tips and tricks you can share? Last night I tried to using time machine to back up my iMac(about 380GB) with wired gigabit, it took 17 hours. I guess its not bad?
