Got 2GB too, which is the most amount of RAM I ever had in a computer, and it felt nice because everything ran faster than before. Even my desktop computer only had 512MB... and the desktop became unbearably slow doing tasks that would otherwise fly in the MBP...
M config. had only 1GB, but there was a promotion going on which gave another 1GB for free if I were to pay in cash (among other things like a keyboard protector, a laptop bag, etc, etc). 🙂
