I want my 12" powerbook 1.5ghz to run faster. It's maxed out at 1.25gbs of ram and has a 60 gig 5400rpm Toshiba 16mb cache hard drive. How much faster will the Travelstar 100gb 7200rpm with only 8mb cache be while surfing the web? I am frustrated that this little machine is sort of slow, and definitely slower opening web pages than the 1.42ghz 14" iBook. In other words, what's the difference in real world time on the 16mb cache to the 8mb cache on opening web pages? I could put in a 80gig 5400 toshiba 16mb too, but want to hear from anyone with the Travelstar. It bothers me that the powerbook is slow at times.
