which pbook to guy: 667/512mb(customized at soho apple store), or 800/512mb?
i was wondering whether or not i should buy a powerbook with 667mhz with 256mb extra memory and Aiport installed OR buy a standard powerbook 800 mhz with all that stuff already in? cost-performance is VERY important ("bang for the buck" as they say), so if i won't see significant differences between the two (like seconds of difference on high intensive apps don't mean THAT much too me... i use the standard premiere, after effects and bryce, but nothing much more beyond that). btw, i've currently on a P3 550 mhz, 128mb ram, ati rage 128card, sony vaio; how much of a difference in speed (to render stuff, for things to load etc) will i notice from the aforementioned powerbooks? sorry for all the number of questions, but this is my first time buying a mac, and it's a very expensive decision (but wise of course), so i need all the advice i can get from the most knowledgeable ppl on the net about macs. thx.
