It's also Linux based on a properly supported distro that is maintained specifically for the rpi. You can do real hacking, not "try to get this to run" hacking.
Seriously. That counts for a whole lot. Frankly, that was one of the great things about the old 8-bit computers. They were constant in some ways. You could turn them on. And then go.
What we've got here is something a lot like that. But it has a lot more power connectivity. All the things the simple machines don't have. But it's all still pretty lean too. I'm excited.
