I just wanted to share this with you guys. http://shop3.frys.com/product/5503990 Fry's is offering 4 GB of Macbook RAM memory for $25 including shipping after rebate! This is a HUGE discount! Anyone looking to upgrade their Macbook's memory needs to take a look at this. I used the Crucial software to determine what my system would need for an upgrade, and the specs match identically. FYI, my Macbook is the last edition (before the recent release). The white with the 2.4 ghz dual core, 2 GB RAM and 160 gb HD. Had it for about two months. HAPPY UPGRADING!!!
