hey well first of all as was mentioned above it is not the computer that makes the design it is the designer.
An iBook will be fine, yes a desktop such as the imacG5 or even an emac may be faster, but up until recently i have been working on an g3 400Mhz imac (was a red one ). If your using the apps that one would assume you will be using in graphic design or even web design the main thing is to make sure you have ram, and lots of it. I know people in the industry (graphic designers more then web design) along with myself who work extremely well on older machine, and even more who work on ibooks. Yes if you can afford the cash and you want something portable the powerbook is the better option, for nothing more then the extended desktop (it is mighty hard working in front of a small screen for long periods - especially in photoshop or illustrator - in my opinion), however as you said it is $1000(cant remember exactly??) extra for the powerbook.
Apple updated the ibook range last night (for me here in aus it was last night) and the 14 inch ones would perform pretty well for what you would be using - and you can always get the hack so you can span the moniters. Just make sure you remember, you can never have too much ram
Well welcome to the industry,
