Consider that a Raspberry Pi costs $35 (for the higher end model) and for that money you get no case and no power supply. Now look at what you can get for $45, or perhaps a bit more if you want a more powerful device. If you were going to use a Raspberry Pi with XBMC or some other media center software, you might want to wait until the reviews for this device come in (we’d love the chance to review one, if anyone from SolidRun happens to read this!). Note that it has optical audio SPDIF out, which is something the Raspberry Pi doesn’t offer!
