Hello, I am happy to say i got my first Mac (and first laptop) last friday. I went to the apple store and got my brand new 1.83 white MacBook. I have two questions for you guys. 1. I am looking to upgrade my ram, i know apple reccomends installing ram in pairs so would i get more performance from replacing one of my 256 chips with a 1 gig stick or from 2 512 sticks. 2. are there any suggestions on things to get for my mac besides ram and case (getting one soon)?
