I upgraded my Macbook to 2 gig of ram this weekend. I’m amazed at the difference from 1g. To be honest, I wasn’t expecting a huge difference. My gaming rig I notice the 2g in games only; not so much in day-to-day stuff. But, with how much I have running on the Mac (Entourage, Word, Camino, Firefox, Adium, Quicksilver, and the real memory hog: Parallels Desktop running XP in a virtual) the computer is much more snappy. Before, it would kind of have that “I ate too much” feeling when I tried to do too much. Now, I barely notice a slowdown.
