I must admit that I don't like wasting materials or parts, I guess a bit of my old-style upbringing has something to do with it, always trying to repair or reuse what I can, partly to cut costs, partly because tech waste disposal can be a hassle and partly because they are stubborn and once I get used to a machine I prefer not to change it unless it is unavoidable. In fact, I am the type of person who uses a cell phone for years and years and years... until there really is no other choice but to change it because it can no longer be repaired or because the applications no longer want to run on such an old cell phone. :)
