This thing totally works.  It's a little windows PC in a teeny little box.The only complaint I have is that even though it's quite small, it's still just a smidgen too large to fit in the HDMI port without bumping into the other connectors.  I had to buy a short HDMI extension cord ($5) to make it work out.I've used it to play 1080p videos that I've downloaded from the internet.  That's all I care about - windows has all the best codecs.  And it's fast enough to do that.
