So I got my white unibody macbook about a week ago (my first mac, btw, and I love it) and I have a few questions about the ram. I installed CS4, but I when began drawing, I noticed that the pen lagged a bit. (More so than my 1 1/2 year old Dell desktop at least) It's not huge, but it's pretty annoying. I'm also going to be installing Final Cut soon too. Would upgrading the ram to 4gb solve this problem/at least help it out? Thanks.
