I love my mac. To bits. There's just so much about it that I adore over Windows.
There are no drivers for any hardware, for instance. You plug in an external keyboard, it has you type out a few letters, and it's automatically calibrated. You don't have to mess around with any of that.
Even a lowish-end Mac can run way more programs at a time than an average PC. I'm usually running at least iTunes, Firefox, Photoshop, Skype, Adium, and Azureus, and there's very little extraneous loading time like you get every time you move the mouse on a PC.
Macs are far more user-friendly. Organizing things on a Mac is way easier than on a Windows computer because you have the ability to switch between different programs with Exposé, which is basically this:
All the windows shrink so you can click on whichever one you need. There are a bunch of things like that on Macs too, like the new Spaces and stuff.
That isn't to say Macs are perfect. They crash occasionally and the hardware can be bad. But since Apple makes the hardware too, all you have to do is send your computer away and you'll get it back generally hassle-free. But the fact that, for example, when I broke my keyboard on my Mac, I just plugged an external one in and used it even though it was bulky and annoying instead of switching to my PC again shows that even when it's bad, it's better than a PC. Usually.
