Hello, I am a long time reader of this forum and finally decided to join as I am going to get my first 13MBP. I will use it for e-mail, internet, writing papers, Matlab and SPSS and also want to run WinXP in Parallels to use scientific software. I only consider 13MBP as 15 is to big for me therefore would be glad for the advice which one to get. I was thinking about following options: a) high-end stock 2.66 b) low-end 2.4 with 128SSD c) low-end 2.4 with 8GB RAM or any other possibility? Please advice.
