I have my 1.33 GHz Powerbook 17 on the standard 512 MB of memory... I think for Christmas I would like to improve my memory to the max avaliable, 1GB (according to Apple Store online). Unfortunately, I am not one of those computer-freaks, and I don't really know/want to remove/add memory to my computer (knowing me something will happen ) Anyways, the Apple Store has a MSRP of $700 to add 1 GB of memory for a Powerbook. Although this seems expensive, I (and my parents, actually) would be willing to pay for this. Why do I want to add? It seems like the pb is not quite so fast, and I see the beachball A LOT. I think the memory would make the computer work/seem faster, no??? But here's my question- once you buy the memory, how do you install? Does Apple expect you to do it yourself? Or can I just buy the memory at the actual, physical Apple Store in a mall, and (bring my pb ofcourse) have them install it right-then-and-there? any info is appreciated!
