I keep macbooks longer, but PC laptops I've had would often start breaking in ways that were too expensive to be worth repairing around that time. I had a Dell XPS whose screen had issues and replacing it (some custom touch screen that didn't have many options aside from dell's official replacements) was something like €600 (conveniently this happened shortly after the extended warranty expired), which at that point in the laptop's life was not worth the expense.
