I think my work machine is still running on 512. It's definitely slow. I am such an efficient, multitasking worker that my machine can't keep up with all the programs open and being used! haha. I have a few questions... 1. Where is a good place to buy ram for it at the best price? What brand should I go with? I havent really heard of ram that is particularly "bad"...but maybe there is a cheap brand that works well? 2. How difficult is it to install ram in the models right before the intel machines came out? My home mac was simple, there was a little gate right under the apple logo and it popped right in. I havent looked - is it as easy as that or am I going in through the back? 3. These hold 2GB correct? 4. Anyone have any for sale? Thanks in advance for the help!
