I spent $2500 on a MacBook Pro back in 2007 and got 7 years of everyday usage before I retired it to be used as a home media server running Plex. Got another year out of it before the hard drive finally crashed. A simple formatting would have fixed it but I opted to replace it with a 1TB hybrid drive for $100. The damn thing is still going strong. In the beginning of 2014 I got a new MacBook Pro Retina with the discrete graphics card for about $2500 and I fully expect to get at least 7 years of use out of it.
