http://www.uhbooks.hawaii.edu/computers/ See the four Macbooks listed in the "MacBooks" section? What are the differences between the MB063LL/A and MB063LL/B models besides the processor speed and price? Does the cheaper one NOT come with Leopard? Does the cheaper one come with the LESSER amount of video ram (64mb?)? I'm buying one for sure tomorrow, I'm just not sure which one. Help a brotha out?!
