I found this forum really helpful. After reading different posts, I have finally decided to go for the G4 1.33 15" PB combo drive. As ppl have said here, it's worthwhile to upgrade the HD to a faster speed. However, from what I seen in apple.ca (Canada's apple website), the only upgrade available from 60GB @ 4200 rpm to 80GB @5400rpm. Is 5400rpm good enough for graphic editing, like photoshop, illustrator etc. Or I should go for 7200rpm? Is there anyway to upgrade to a 7200rpm HD on a PB? My other questions is, for the HD upgrade, do you think I should do it when I ordered the machine from apple.ca? Or I shall do the upgrade from somewhere else, considering that it is a lot cheaper and more choices available.
