Go to newegg order 2gb ram from G.Skill and install in your macbook.
My labtop is a beast with the added ram, before with only 1 ram it ran good start up took about 40 total seconds about like 30+ programs would bog it down .
With 2gbs ah man it CRAZY system starts in about 15-25 seconds fast fast, programs well lets just say I got tired of running programs that would bog my system.
Internet, audio, video, all kind of ish system runs beautiful. I truly beleive this is the efficiency of apples OS and not neccesarily the hardware but a combunation of both.
My next upgrade will be removing the 80gb hardrive & installing a 160gb 5400rpm. Really wanted to go with a 7200, but currently manufacturers only make a 100gb.
Yeah man my macbook, minus the problems I have with my superdrive ( which will get fit) is amazing!!
4 out of 5, reason for not a perfect score is due to the lack of a graphics card and limited usb/fire/other connections. But I fond ways around all that
, peace
