I switched over from a PC to a Mac about 3 years ago, both desktops. I've come to like the Mac more... Personally, I like the fluid navigation, the displays, layout, and aesthetics, its usefulness for the art field, and honestly, the better experiences I've had with their tech support. My school is pretty much completely Mac-based, so its a matter of convenience for me. I work with Photoshop, Illustrator, or InDesign nearly every day, and I favor them on Macs anyway. The cover-flow display is very useful when I'm reviewing portfolio spreads outside of a program. It's not a flawless OS, of course. The gaming is meek at best, and it can sometimes be annoying to know that if I ever felt like revisiting old computer games like the Tycoon series or the Sims, their cost is ridiculously high. I don't have too much of an issue with the high price of Macs themselves, since I think that it's really only the laptops that are too expensive. As for myself, I received a 20" Mac desktop and I believe it cost somewhere around $1200 which isn't too steep. I MUCH prefer desktops over laptops anyway, mostly due to the fact that I get a larger display for much less money, and because I have no need to take my computer anywhere.
While I'm a big patron of Apple, products, I will admit that I usually hate their advertising campaigns. I think they're pretentious, uninformative, and stereotypical. Thank goodness we don't see much of those "I'm a Mac and I'm a PC" commercials much anymore. They were snarky, and spent more time bashing the business competition than talking about the pros of the product. Not to mention, the two characters were totally overblown representations of the customer base. They make it seem like the only people that use Macs are cool, hipster-type 20-somethings. My Dad is in his late 50's and has been using Macintosh for music/audio production since they came on the market. People get so wrapped up in Mac vs. PC it gets a little out of hand sometimes. One friend of mine on Facebook posted a huge chart of "Why PC is Better Than Mac", with a comment underneath saying, "Macs are for people who do not know how to use computers, and are willing to spend thousands of dollars to justify their lack of technical knowledge." Seriously. That's just plain rude, especially for me.
...rant over. Anyways, I guess I could sum it up by saying I prefer Macs, because they're the standard for the industry I'll hopefully get a job in one day. I'm already fluent with the OS, so of course I'll like it better than others, but I couldn't care less if someone operates on an OS different from mine, and I certainly won't chastise them for it.
