Thanks - (it was on the 24th - same day as Jim Henson's)
Yes, it's a very small computer - about the size of a deck of cards. This model has 4 USP ports for keyboard, etc, an ethernet port to wire into the web, and HDMI (now a standard) video to plug into a monitor. There are no disk drives built is, so it works on a micro SD card.
It's pretty neat if you're geeky. It can be used in robots & whatnot because it's so small. It's been a long time since I've beat Unix or Linux so I have to re-learn a few things.
