With the majority of users being PC users, the majority of users are used to the usuall look of computers, with Apple attempting to switch those guysto Mac's, there main focus will be getting them to be the iMac, but (unrightly) alot of people dispise the look of the flat panel, and when it comes down to it alot of people are afraid of new things and alot of people can be put of by its design, after all design does mean alot now in the tech world, so mabye Apple needs to introduce a new desktop line, like a first step for switchers?
