They're a pretty cool gadget, really come down in price. Seem to remember they were like $200 or $250 when they first came out.
The instant netflix is pretty sweet for just getting on and browsing for a movie that looks interesting, but it usually disappoints if there's a specific title you want....only a small fraction of the Netflix library is available instantly, some movies are only on instant for a limited time then vanish again, ect. Sometimes a few seasons of a show are on instant and the rest aren't, or the sequel to a movie is available but the first isn't, you get the idea. No real rhyme or reason to it.
