I'm a confirmed Mac user, although I have to use Windows at work. Mac hardware is indeed more expensive than equivalent PC kit, although not that much more expensive. The problem is that Apple don't make any 'entry-level'/cheap stuff, so you'll always be able to get a cheapo Windows laptop or whatever for much less than what a Macbook would cost.
I run a few Macs, my main machine is a 2012 Macbook Pro Retina with an I7 processor, 16GB ram and a 500GB hard disk. I run Parallels as a VM to seamlessly run Windows applications alongside OS/X stuff. It's just as fast and reliable today as it was the day I bought it, whereas before I switched to Macs I tended to buy a new laptop every couple of years.
One canard that is often touted around is that you can't get under the covers/technical with Macs, which is untrue. OS/X is a Unix variant, and all the unix techie stuff is all there should you want to furtle.
