I downloaded and everything seems fine after re-installing audio and video codecs, Couch Surfer and vim. But yeah, it wiped out everything I had there previously. I wasn't running Boxee, though. Took it off after they cut Hulu.
Kidding obviously but question: how useful have you guys found ATV? I have a MBP and just hook up to my tv to watch iTunes content. Isn't that what ATV essentially does or is there more?
Depending on your individual needs, you could either love it or be indifferent, but I think all AppleTV owners love this little "hobby" device.
