I'm planning on buying a 12" powerbook. I've got it all built and saved on apple.com, but i'm not sure if I should wait or not for Macworld Paris, as I'm not sure if there are much plans for an updated version? Any insight would be wonderful. Thank you. PS. I would need it by the end of september, so if there is no chance an updated one would be out by then, please say so. Thanks again.
