Wow. I bought a Mac Mini (as well)
After carefull consideration my impatience won and I bought a 2.0ghz with 2 gigs and a 160 gig hdd. It was more or less by accident, I thought I had two more buttons to push to confirm it but it was only one! So in three days Ill have two machines humming on XBMC. When a big milestone is hit, say v1.0, Ill be sending beermoney as well!
