Practically speaking: iTMS TV
As I write this, 34 people with differing opinions have commented on my post from the weekend about the 320px size of the iTMS television shows.
Pictured with this post, you'll get a view of the way I've been watching shows I've grabbed off the iTMS: shrunken in the bottom right corner of my screen as I busily scan Bloglines, post to TUAW, chat, and work on various other projects. The sound is crystal clear. The picture is small, but at this size, it also is crystal clear. It's replicating my long-standing habit of working on my homework / studies / take-home work with the television on in the background. This has always worked better with reruns, as I don't get distracted. The TV provides just enough background noise to help me edge out daydreaming and to stay focused on task.
Except now, I can take that TV background noise with me anywhere I go. And from the looks of things, I'm not the only one who finds this very appealing. Sure, I've had the ability to do this myself by grabbing shows off my ReplayTV for a while now, or even converting a few DVDs, but this is easier and faster, and the time I would spend converting the videos otherwise is easily worth the $1.99 price of entry.
