PCs have their good points (do you have an hour or so to wait while I think of one?), but having switched four years ago I doubt that I'll ever go back to using one as my main machine. Installing and uninstalling programs on a Mac is a dream - nothing to do but drop them onto the Mac HD Icon, no endless screens asking what you want to do or where to store it, no need for Wizards who never are. To uninstall you simply drag the unwanted program to the trash can and it's gone. No little warnings bobbing up to ask if you really want to delete a dll file that 'might' be needed by other applications, no registry to mess around with. Bliss! Add to that the fact that more and more buyers are switching from PC to Mac year by year, plus the fact that both Windows and Macintosh programs can now be run side by side, and what advantage is a PC left with?
Besides none.
