I have had the same Macbook for over 5 years now and it is still going strong. I owned PCs before this computer and none of them laster for more than a year.
I would say there are no drawbacks to buying a Mac. Some people complain about the pricing, but when you buy a new PC every year... you are actually saving a LOT of money by buying Mac.
Good luck! If you have any questions, let me know (my DH is Apple certified along with all the other certs), so I have a built in Apple genius at home
