Hello everybody, I want to buy a MacBook Pro, but I don't know wich size. I'm choosing between the 15" and the 13". I'm leaning towards the 13" 'cause of its portability. I won't buy it until they upgrade it to the new Core i processors though (don't need it immediately), 'cause I'm waiting for a 13" comparable to that one: http://www.sony.it/product/vnp-s-series/vpcs12v9e-b If they won't produce something like this (with maybe a bit more pixels) in the next upgrade I'll go for a 15" or for the Vaio. I'd always bring it around with me, that's why 13" is so attractive. For heavy work I already have a Mac Pro with big displays, but I want to be able to use Adobe CS5 and CAD programs when I'm away from the Mac Pro. Is 13" enough for working with these programs?
