Hi guys! I hope you can help me decide which 15" is more suitable to my needs, I'm a graphic designer using Illustrator, Indesign, Photoshop and soon will be using Dreamweaver, Flash and Fireworks for web design. I came from powerbook 15" G4 2003, so you can see that I'm NOT that guy who upgrade every 1-2 years. I just want a machine that will last for a long time and not break the bank. Thanks in advance!
