Hey everyone, this site & forums have been very helpful in my Mac research over the past few months, thanks! I've decided to buy the high end white macbook and I'd like to add 1GB ram to it myself. Is this a notable improvement or should I fill it to the max usable capacity (3GB I believe)? I am waiting until Macworld to see if new notebooks will influence my decision on the 2.2GHz macbook which I would get with a student discount. I've heard of some kind of keyboard protector, snap-on cases, and also a self adhesive palm rest that can be used on the notebooks to help reduce the wear of the macbook plastic and keep it super fantastically clean! Have any of you had personal experience with these types of products, or any comments on their contributions to macbook overheating? ...Or is it better to just clean the macbook often with the magic eraser and such recommendations given in the forum without inhibiting its performance? Also, is Applecare worth the $, and would you be able to get a notebook repaired even if the issue didn't concern manufacturing defect? Applecare extends my warranty service to 3yrs, could I purchase a kit after the original 1yr is up or do I have to buy it right when I get my macbook? Thanks for any advice! I have a lot to learn; this is a big OS switch as I've wasted a lot of time learning how to deal with you-know-what's OS.
