I'm not particularly careful with my devices yet I never had something break in the last decade - however, 2 out of about 6 Macbook power adapters have had their cable messed up and needed replacing, without any obvious reason. Ironically, the more abused power adapters (i.e. mostly taking to work everyday) fared better and are like new (except dirtier).
