The AppleTV gadget looks neat and has a good price but a closed product tied to one supplier of content isn’t going to tempt many people until it has some actual content. The UK iTunes store currently offers 0 TV shows and 0 movies.
I can buy* “Tin Toy” and a few other Pixar shorts for ¬£1.89 each, but so far that’s it.
Of course, if the AppleTV box can run MythTV I’ll be queueing up to get one. It’s good value at ¬£200 just as a remote iTunes node, even without the video features.
(*Buying DRMed products isn’t really buying in the traditional sense, of course. You just borrow them from Apple)
