The newer computers have many people angry, as the idea that you will have to buy an entirely new computer after 5 years is kinda repugnant to most people. I have the older Unibody from 2008, and I bought it when in came out for a hefty $2,700. It has never had a problem, and I love it. The battery gets about 5 hours with the screen/keyboard on ambient light sensor during a flight, one core turned off, Bluetooth off, and Airport off. Plenty enough, and the computer seems to have a better display then all of the brand-new computers at the Apple Store... None of the funky issues with the screen, the build quality, or anything else. I just have the impression that Apple put a bit too much thermal paste on the GPU and CPU, because the computer heats up during ordinary Mac Rumors browsing... Left side only, the right side is never hot...
