Anyone have any information (or opinion) on the best way to beef up a new 13"MBP? I have a 500gb Western Digital Hard Drive in my white MB, and am wondering if I could swap it into a new MBP, or if there is something "new" that wouldn't allow that. Also, what sort of memory should I load up into a new 13"MBP - That is, if I dont want to spend $1k upgrading to 8gb. Are these the goods?: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231213 Thanks a lot!
