I have one...it's ok but like Schumi said, it could be so much more. Streaming from my desktop is worthless because it's so slow. I have not taken the time to set up my 5 ghz network so it might be better.
I just bought one of these
Amazon.com : G-Box Midnight MX2 Android 4.2 Jelly Bean Dual Core XBMC Streaming Mini HTPC TV Box Player : Hd Dvd Players : Electronics and really looking forward to it.
The Chromecast was just as easy to set up as advertised, FYI
