hi, i was wondering whether everyone thinks it would be a good idea to upgrade to 2gb on my macbook from 1. I use CS3 occasionally, but i don't turn my computer off very often. http://www.datamemorysystems.com/AMM21.asp (the second one) i have a 2ghz core duo, with an 80gb hard drive. I am going away to highschool next year, and was just wondering if it was worth it.
