DH says upgrade to 4GB for $100 now, I want to save $ and stick with the 2GB. Would the 4GB speed up page loading? I do have multiple windows open. I am light user, surfing the net, home photos. I am buying to share with DD in college, so have to buy before the 8th to get her the itouch. Other little Questions Anything else I need to know before buying? I just upgraded my imacG5 successfully with Crucial and it was easy, same with MBP? I am going to wait on Aperture thinking version3 might be around the corner?
