Mine's 7 year old, and to be fair, it's working wonderfully still. I'm going to save up for something hugely better next time, though. Most computer parts these days are built to be slim and compact, which is why laptops these days are featherweight compared to their predecessors.
But as a result, they're usually not replaceable, so repairing and maintaining them can be a bitch. Really different from the old days, generally better, but a bit worse, too 🙃
