WD TV Live (2011)

Pros: Plays basically any format including Blu-Ray in MKV format with subtitles.
Nice Spotify App.
Can stream media via Network or Local USB Drive.
Great looking interface.
Works with wireless or USB Keyboards.
Frequent firmware updates.

Cons: Occasionally freezes or becomes sluggish.

Summary: This is a great media hub! I've streamed blu-ray quality films (MKV format) located on both a locally attached USB HD and NAS device and it plays flawlessly. It will also detect media on other shared computers across the network. I absolutely love having the Spotify app for playing music via my Receiver. This thing occasionally freezes, but I say that's never been a problem while watching movies. It also has Netflix, Youtube, MLB, and a host of other services. I highly recommend this device due to it's ability to play basically any media format.
