Roku XD (2050X)

Pros: Lots of free content. Linking to your Netflix account is trivial. Comes with a free month of Hulu-Plus ($8 a month subscription thereafter). Also links to and plays Pandora (free) music. A bunch more, as well.

Cons: Mine came with a dying video encoder (intermittent lost sync, some horizontal lines in the output of everything displayed). But Roku made it good and sent me a new unit right away.

Summary: Despite one review claiming inability to get a wireless connection, the whole installation and linking to accounts was trivially easy (hey, buddy, update your crappy old wireless access point). This is a no brainer, relatively cheap TV add on that gets your Netflix account onto any TV within range of your WiFi router. But it plays a lot more than Netflix, too, which is worth your considering. For about $80, its been a lot of fun, and you are not tied into a proprietary content system like Apple TV. Nice alternative. I'll be buying one for my sister and her husband as a holiday gift very soon.
