I own a Mac mini that hooks up to 32" LED TV. I'm running Windows 7 together with OsX via VMWare Fusion with full inter OS file support and even drag and drop between OsX <> Win7.

I have always used Mac and did own a PC for a long time just to do stuff that would only be possible on a PC. But now there no need for a second computer.
And yeah, I could run Linux next to Win7 and OsX if I wanted to.

My experience is that compared to a PC a Mac requires much less maintenance and is usually less prone to software issues. I prefer maintaining a Mac over a PC because I feel more 'at home' with a Mac than with a PC. And that's all there is to it, you should run the computer you're happy with. Try to test drive a Mac and then make up your mind.
