Yeah, it's main use is for running as a media server. I've been wanting to try out XBMC for my home theater setup.
For $40 to my door, I couldn't be more pleased. The next closest option is around $100+ (Pivos Xios) and that doesn't run nearly as well. Other alternatives are jailbroken AppleTV2 (no longer available so running $200+ on ebay), other small nettop ($250+) or build a small htpc (much larger, heat, power consumption, etc.)
This thing runs on a cell phone power supply, 700ma, probably draws half of that.
Very slick, I love it. XBMC 12 just went final a couple days ago, Raspbmc should be updated to final in the next day or so, if not tonight.
The best setup is to install it to usb thumb drive, SD card is for boot only. Very zippy this way.
RC, give Raspbmc a shot running from a usb stick, I think you'll be surprised. It's a one-click install, and Raspbmc for your version should run fine.
