Hi all, I'm guessing that some of you out there will use either of the Macbook Pro 15" or 17" versions, so I could use your input please! I'm going to start working for a couple of clients away from my home office so need a Macbook to work on when I'm out and about, and while I always thought that a 17" would definitely be the one to go for (ie for the sheer physical size), other people have said that a 15" is ample size, and there's also the issue of the 17" being bigger to carry around - anyone any experience/recommendations ? many thanks
