Certainly in consumer electronics, many things don't last as long and are difficult / impossible to repair as indicated above. Even business laptops, which are intended to be repairable, are getting worse - had a fairly new model of business laptop repaired yesterday under warranty (it needed a new keyboard). In the past I'd just have told them to send me the part and I'd do it myself (on earlier models, a keyboard change took about 2 minutes). However, on this recent model it's a complete dismantle job (motherboard out, etc) because it's now mounted from the bottom rather than the top - a good example of form over function. I decided I couldn't be bothered to do it myself so they could send a technician (and it took him 20 minutes, despite no doubt being familiar with where all the screws are).
And so far as repairability computers are some of the best items for this in the consumer electronics world - smartphones, tablets, etc, tend to be far more difficult / impossible to do anything with, depending on the brand / model and what's wrong with them. Apart from at the high end, things such as radios, CD players, etc are rarely econimic to repair.
And of course many white goods now fall into this category too - either because they are designed to be too difficult / expensive to repair, or because the parts are too difficult to obtain.
