Apple is back in the news with a new and thinner iMac, a new iPod that does video, and a new iTunes (6 and following 5 by a few short weeks). The Stuff site has a nice and short review covering the important points.
The new iTunes store will sell music videos and a few TV shows, including Lost. I just started watching Lost DVDs from the first season and I might try a purchase if iTunes is selling the current season. The shows cost $1.99.
