I was windows all my life (about 19 years now). Desktop after desktop, laptop after laptop and I decided to go Macbook a year ago... best choice I ever made. The price was off-putting... but with discount I bit my lip and bared it.
Still runs like the first day I turned it on. I have never had any issues with it, turn it on and works like a dream.
Granted, you do get more spec for your buck with windows, but apple appears to be built to last.
