hey all, i am a high school student that is interested in the graphic design field. i do freelance graphic design work, such as logos/banners/business cards. all of this work is done on my desktop at home. i have recently decided to go "portable" and had my eyes on mac laptops since they have such a high reputation for the multimedia user. well the thing is, i'm new to macs and don't know where to start. i was wondering if anyone can help out recommending a setup for a mac laptop. as for what i am looking for, i like to have a fast laptop capable of multitasking. preferred screen size of 15" or above. and maybe a recent generation with intel processor. i am on a low income at the moment due to school work, and i find myself out of the house very often and so i would like to find a laptop to do some "work" and increase my portfolio. i would probably spend about 800ish. so if you have any recommended spec.s that would be great, and if you are selling your laptop (g4 + beyond) offer them up. thanks a lot.
