I see Retina Z2-4mb boards posted occasionally on c.s.a.m. Would I be happy with this card running NetBSD? There don't seem to be any Z3 cards for sale on c.s.a.m lately, and retail ($600 plus US) seems a little high to be investing in this box - at this point, at least. Esp. with the power-pc boxes lurking in the near future. Comments? -- dick
