i'd like to buy a 12" power book. im sick of waiting of updates. but say i buy a 12"pb with the dvd-burner and maxed out ram (620 i think)and 60gb hard disk space. how would it compare in speed and handling to my p3-866 PC with 256 mb of ram? people always talk about how you cant compare the speed of macs and PCs, but a 866mhz powerbook sounds awfully slow. and i've heard the lack of L3 cache is a problem sometimes. i read in mac world magazine that the lack of this is noticeable. by the way, ill be using it mostly for fairly heavy graphics use and my p3-866 can hold up pretty well. i've never used macs really and i dont know what to expect.
