So I currently have a first generation MacBook Pro that I bought as a recon from Apple. My company is doing well, and I've been offered the chance to upgrade--even to the 17" screen if I want. I originally bought the 15 as a compromise between portability and the extreme lack of cool (my own opinion) offered by a plastic case...something about the brushed metal look is just better. Anyway, I've wound up not traveling a lot with it, but I already have the protective sleeve and Wenger back pack for the 15...and originally I said I'd be happy with just replacing it with a new 15", but since I said that I've begun to waffle. I have no experience with a 17" laptop, as far as weight and size go, so I have nothing to measure it against. I'm not certain the extra couple of inches of screen size is worth it...or not. So I know we've got a couple of Mac guys here, and I was hoping maybe someone could offer some helpful opinions (you know, like...of course I want the 17. Duh, it's bigger, that means it's better, right! LOL).
