I like Apple mainly because of their quality product line. Quality does matter to me, and I don't mind spending extra bucks to get top of the top.
I have a quad core PC machine back home that rocks, I paid around 2k$ for it, but I love my macbook pro because it's also very fast and the operating system is amazing: finely tuned, stable, fast!
The best of all, MacBook Pro is at the same price range as its level competition, like Sony Vaio or Dell XPS. It's not much more expensive than those, yet it has better hardware and boy it is so sexy
The same goes with iPhone, iPod touch, iMac, and so on and so forth.
