I’ve just downloaded the first season of "Lost" from the iTunes Video store. I agree completely with C.K’s comments over at tuaw. Even if the format might be considered "small" by some people, I think the format and distribution channel should be supported.
Since it’s introduction, I’ve become a real fan of the iTunes Music Store- I very rarely buy physical CDs anymore- usually only if there is a DVD included- and this is something that is going the way of the dinosaur with Videos being included along with the music.
I don’t have the new iPod with video (yet), but this will make my evening commute much more fun. Also, since American shows tend to run 1 season behind, I can download the entire season in one fell swoop- at an attractive savings per show.
