Just learned about this compact, and inexpensive PC: the Utilite.
At this point its just announced, but the company has a prior product line called the "Trim-Slice", so they do have a track record.
For about a $100, you get a small (very small) case with a powerful CPU, 4G Ram, 128G storage, and plenty of connections (USB, Gigabit ethernet, etc). Can run Linux or Android.
So now yet another power small computer that could be used for some interesting activities. A possible competition for the Raspberry Pi or Beaglebone. (tho I don't think so, they are focused on different markets).
