I bought a MBP in 2012. The motherboard went bad after a year. And after a year the cable to the hard disk had to be replaced. Also I feel the upgrades we do on OSX causes the MBP to slow down. It is sleek, elegant, battery life is great (actually I need to replace it now, its dying), great design etc. But I feel the more perfect it is designed to be, the more vulnerable it is. I say this when I compare this to my HP pavilion sleekbook which did not have any trouble so far in the last 3 years.
