I'm still waiting for the new iMacs, but I was planning on getting the 17", but i'm really unsure if its big enough for what i'll be doing. Right now i'm going to school for advertising, and i'm looking into graphics design on the side to get an overall skill in the creative field of advertising. I'll definitely be creating faux full-size ads and possibly working a lot with Illustrator, Photoshop and InDesign CS3. I'm just unsure on whether 17" will be enough. I know there is always room for a second display, but i'd like to know ahead of time so I can either buy another monitor or get a larger iMac. So, what do you guys think?
