I have Apple's for years & years (if I told the model that I originally had, I'd give away my age :D). There will NEVER be a PC in my house. Trust me, having worked on PCs and going to Apple…you will LOVE IT. So intuitive and pleasant to use. My brother who knows NOTHING about computers easily figured out how to use a Mac.
I've had the most expensive to the least expensive...now I have a middle of the road MacBook and I love it. I've had it now 3 years, and it has never crashed once...and I am a heavy duty user (graphic designer) and use huge memory hog programs (including photoshop, indesign, illustrator, etc.). The key is always putting in the max memory that is allowable (and then some...if you know what you are doing).
BTW, I also have a MacPro (quad core) with dual Apple Cinema displays at work...and at home also a Mac Mini, 3 iPods, an Apple router and a 3g iPhone...yeah, I'm an Apple fan. :D:D Their products just work!
