mac or pc

I've had my macbook for 3 1/2 years, the only issue being... I wore out the $130 battery. Whenever I've had problems navigating the software, I've been able to go to the apple store in the mall, and a genius geek has fixed me up. No slams on the PC, my neighbor is a former Microsoft geek, and he swears by windows 7. After purchase service would be my question with a PC?????
