I'm wanting to upgrade my 1ghz PowerBook and am considering a last version 1.67ghz PowerBook or a referb MacBook. My main system is a 1.8ghz DP PowerMac and I use all non-Intel friendly apps -- Quark 6, CS2, iLife 05, Office, etc. All my apps are up-to-date and somewhat pricey so I don't plan to upgrade them any time soon (I like to go every other -- ie CS2 to CS4 and CS3 isn't even out yet). I use the PB mostly for personal use, but keep it as a back up system to my G5. I'd like something that runs a bit faster -- plus I can write off any purchases as a 'o6 business expense if I act fast. Considering all my apps are not developed to run on an Intel system what would be faster, the last version 1.67mhz PowerBook or a MacBook? I've read where the MacBooks are actually slower -- MUCH slower than previous G4s running CS. Secondarily I'm not sure if I'd like a smaller screen. Does the MB have a smaller pixel per inch count? How does brightness compare? Thanks for your help.
