I would say it is even worse when considering tablets and smart phones, and maybe even laptops (although they have a significantly better shelf life than tablets and smart phones). They are garbage the moment the battery ages out. For some tablets, that meant one or if very lucky, two years. That's a lot of nice screens to the bin for something that otherwise should be trivial to replace.
