For me the price point is a no brainer. We already pay Netflix $8/month, so even though it'll be spread out over a few months, this will ultimately only cost us $13-14 after taxes. I've been waiting for an Android-like solution to compete against Airplay (we have Apple TV), and this looks to be it, with even more options potentially. I just checked and a lot of the Best Buys around me have them in stock, so I'll probably drop by and grab one today sometime!
The only thing I can't seem to find is whether or not it has to be plugged in constantly to it's usb power source, or it just has to charge every now and then. I'm guessing it's the former, but the videos I've seen show it plugging in to the HDMI port without being plugged into the usb power source.
