Interesting, I just read a report on the differences between 4200rpm and 5400 rpm drives on a powerbook. The conclusion is that it is probably the best upgrade you can do for your powerbook for the money. Going for the 7200rpm drive is not nearly as cost effective and will apparently void the warranty.
