Right now I am watching the first season of LOST, in 5.1 HD, with a crisp picture, and looking forward over the next several months to re-watching the entire season. Queued up are also Battlestar Galactica, Eureka, and Jericho. $8/month is cheap for the quality entertainment I can get.
I used to have the DVD service from Netflix when it first came out, and it was very frustrating, hard to get the movies I wanted, and the discs were often in really bad shape when they arrived. But we were in Colorado and didn't have a lot of options. No interest in the discs today, but the streaming seems like a bargain. Might cancel a movie channel or two from Dish as well.
