I think I have been fairly lucky on the expensive computer front, and almost all of my computer lasted for more five years. In fact, a laptop I have from the 2009-2010 era still boots and works well, though the trackpad needs some attention, as clicking difficult. The key in this area is to find a good brand and line from that brand. Then again, seeing as how computers are being made now
