I use a PC at work and a Mac at home. (In fact, even though my company has adopted laptops that we can take with us, I have a Mac laptop of my own.) As a practical matter, the Mac works better for me - fewer strange things happening, smoother operation in general, less frustration.
My specific favorite example of how simply the Mac operates is backups. I have two backup drives for my MacBook Pro, one at home and one at the office. I just plug them in when I want to do a backup and the Apple software makes it happen. I don't have to tell it which backup drive I've attached or tell it to do the backup. (I'm not saying a comparable feature doesn't exist for the PC, mind you, just that it's very easy on the Mac.) (My favorite, so to speak, example of frustration with PCs is that there's no consistent approach to where the computer thinks you ought to save documents, so if you want to save documents from three different pieces of software, you may start in three different places and have to figure out how to navigate to where you want to go each time.)
All of that said, if you're thinking seriously of switching, spend some quality time with a Mac before you buy. There are definite differences in the operating systems, and you may find that you like the PC better.
