It runs Red Hat but I am ignoring that. The Space Cube is an interesting little device (Link to Manufacturer). Check out the pictures of the Space Cube next to a cell phone to get an idea of how small it really is. The article linked above makes it sound like this is brand new when actually it has been around for a while as noted in this cached blog article from 2006.

I would just like to see one running Windows!

 

Cheers!
