Living with two sisters who have MacBooks, iPads and iPhones, I've see all the fancy hardware first hand, and it looks far nicer than anything I've see Windows ship out.
Now or course I don't have a Mac because I still play games and can't afford a $1000.00 computer but both of my sisters had jobs and finished university, they now have jobs in London.
Because they use it for work more than play, they can drop the need for a flashy graphics cards and focus on function and apps/programs more than specs.
Now I'm not saying you can't work on a PC, it's just that I've seen stuff done on both. When Vista was the new thing everyone loved, my sister had a desktop with it. It was really bad and crashed tons of times. She's had her current laptop for ages with no problems as far as I know.
Then again to sum things up this is all a personal preference and all I can do is debate whether one is better and in my opinion a Mac is, though that is my opinion and I can't force that on you.
