I updated two AppleTVs but not used v2.2's new features yet. (Still seeing recopying of videos/podcasts after initial (first) playback on the AppleTV. (Next sync from iTunes recopies them over again.) That's been happening here since the v2.0.0 update.)

There's also more price cuts on 4GB (2x2GB) memory upgrades for Mac Pros, Macbooks/MacBook Pros, Minis, and G5's on the Site Specials Page
