I am going to be purchasing a new powerbook in august. I am debating between a 12" 100gb, 1.25gb ram, SD + Dell 20" lcd, or a Maxed out 15" 1.67 SD 2gb ram 100gb. I really love the 15" but will it be too big for the small desks in most college lecture halls? Any college student have the 15" and feel they would rather have the 12"? I have been going back and forth for about a month. I know with the lcd + 12" I will have more screen, but the 15" will have a faster processor and almost double the ram. Anyone been through this? I have a 12" right now, but really wish I had a bigger screen. Portability is a big issue for me but (from what I understand) the 15" is still very portable. I know that what ever I choose I will be very happy, but just curious what others feel. Thanks in advance.
