Okay so I have the newest macbook pro (15" 2.4 200GB 2gb) I want to upgrade the ram to 4gb. I looked on newegg.com and I can get 4gb for $85. It seems way too cheap compared to the Apple memory. What is the difference? Any god suggestions on how to upgrade ram without paying the $400? Also could someone show me to a link of a good 320GB HD for MacBook Pro. I am going to go for it and follow the steps and do it myself. I just need to find one to buy. Let me know.
