Heads up! OWC is now selling the 4GB RAM upgrade kit for MacBooks (and Pros) for $109, $10 off compared to beginning of this week. http://eshop.macsales.com/shop/memory/MacBook/DDR2/ I bought mine earlier this week on Monday at $119 + shipping (technically Tuesday in Macao). Still, can't complain, I already got my RAM today instead of having to wait another week BTW, I'm not affiliated w/ OWC in any way. Just a happy customer! 4gigs of RAM rocks!
