We in studio are amazed with this device and I have finally got my hands on one, while the rest of the studio are now waiting for theirs. Patience is a virtue. At first sight it is slightly bigger than expected although it is still the width of a credit card. To be able to get a computer for around £30 (incl. shipping and vat), while still relatively powerful for it's size is a great step in computing. Altogether I spent about £60 with the extras (USB Hub, SD Card, Keyboard/Mouse, Power and HDMI), and after plugging everything in and finding a linux install I had a working computer.
So how does it perform?
True, it is less powerful that a normal PC, and you can't run Windows on here but actually it runs very well. I decided to try it out first as a media centre, and was impressed how well it played video & music thanks to the onboard graphics controller. Other things it has to think about a little but as it was designed for education this shouldn't matter. Now I'm just looking for projects to do with it.
