The Apple Powerbook looks amazing, is really thin, and can do so much that the PC can't touch - editing movies, iTunes, all sorts of fun stuff. So, I think that disliking change is not really a great reason for not giving it a chance. As long as you have a good Mac professional available to help you through the changeover and answer questions along the way, you should be fine. Macs are very easy to adjust to. Very user-friendly. DD switched over to a Mac from a PC and she says it took her a couple of days to get used to it. Her boyfriend, a devoted PC man, switched over recently and says it's the best decision he ever made.
Also, the Mac store at the Grove has a free class called "Switch at 6" which is all about switching from PCs to Macs. They also have free classes throughout the week about using all the different programs. The Mac desktop, BTW, can be made to look like a Windows desktop.
