I ordered a Raspberry Pi from Element14.com yesterday. I should be getting it in the next few days. I'm not really sure what exactly I'll be doing with it, but that hasn't stopped me before when it came to buying a gadget. Maybe ill try installing XBMC on it and see how that works.
I'm also trying to think of a central location we can have a first meet up. guess it depends on how many people can actually attend. Emails coming out soon to discuss it.
