Sorry guys, i'm sure you're sick of hearing these kind of questions but the quick guide at the top of the page was a little hit or miss. Ok so i'm going to Uni next year to study architecture and i've got my heart set on a fancy MacBook Pro, the problem that arises is the old 15 or 17 inch question. I'm needing portability obviously which sways me towards the 15 but i can't help but be attracted to the bigger screen and better speck on the 17 especially with the 3D stuff and autocad that i'll be needing to use. and thats not even taking into consideration the price difference. Is there anybody that can help solve my problem? somebody doing the same thing at uni and has some insight into the subject? Thanks everyone for input.
