I think the more annoying thing about modern laptops is the lack of standardization from year to year from the same manufacturer (other than the SSD, usually).

I think the more annoying thing about modern laptops is the lack of standardization from year to year from the same manufacturer (other than the SSD, usually). When HP, Dell, Lenovo, or ASUS refresh their laptop, usually the overall design of ports, body, and keyboard stay more or less the same for about 4 years or so, but the motherboard dimensions, ribbon connectors, cooling system, and batteries change for no real reason. A lot of components will have dimensions that differ by only a few millimeters but that's enough to make searching for replacement parts an ordeal. For example, if I could get a Thinkpad X1 Carbon what was guaranteed to have an upgradeable/interchangeable motherboard for the next 4-5 years I would gladly buy one. I don't even get why that's not currently the case, the current Thinkpad X1 Carbon more or less looks identical to the one from 6 years ago. Instead I buy whatever's cheapest every 2-3 years. It's so bad that the EU had to legislate USB-C because this problem manifested itself as hundreds of marginally incompatible barrel pin chargers. It's wasteful and annoying.
