Been searching around lately, but haven't found any input from students in graphic design as to which powerbook suits them best. I'm a second year Visual Communications major, and am finally looking to make the switch to a mac laptop after clinging to the hopes that my PC will get me through the program without a hitch - it wont. I'm currently looking at both the 15 inch and 17 inch powerbooks, and I'm really not sure which one to get. So for those of you in design, I'm curious - which powerbook do you use? Why did you choose it? The 17 is mightily appealing for it's extra screen real-estate which would be invaluable for Illustrator and Photoshop, but I dont know if the extra bulk of the 17 is going to inhibit my mobility at all. I need to take it to and from class everyday (I'll be getting a dedicated bag for it and a sketchbook or two, so fitting in my regular school backpack isn't a problem). So which do you use? And why? Thanks.
