I'm pretty confused. I'm a web design major the main apps I will be using is photoshop, illustrator, and dreamweaver. I like the portability of the 13, but at the same time like the screen real estate of the 15. I will be lugging whatever I get around with me. So weight is a factor, also price is a factor I'm thinking around 1600 maximum I can use student discount to hack off about 100 dollars and some money off things like ram software etc.
