I had to replace my computer because it died.

When talking about hardware, if it works for you keep using it till it doesn't work. But when talking about desktop operating systems, you should be aware when it loses security updates support and try to upgrade to different one that works for you but has better security updates.

My main steed is an HP ZBook from 2014, and it is a powerful and fast computer.

I’m running a 2015 MacBook Pro still. I’m not spending $2k+ on a computer again anytime soon.

My PC is still largely the same, in general spirit, as when I built it (c 2014-2015). But I have had to upgrade some key components over time. First was the move from a 1TB WD Blue HDD to a Samsung 860 Pro 128GB SSD (for my OS's drive), and, related to that, at some point soon after, I moved my games drive from an HDD to an SSD. Next, I upgraded my GPU from an Nvidia GeForce GTX 760 to a Nvidia GeForce GTX 1080. This build state lasted a decently long time until I switched from Windows to Linux, so I switched my Nvidia GPU to an AMD Radeon RX 6600 (not exactly an upgrade, but more of a side-grade) to improve the user experience. The most recent change (last year, iirc?) was upgrading my RAM from 8GB DDR3, to 16GB DDR3. My CPU (Intel Core i5-4690k) is starting to really show its age, though, so I've been wanting to upgrade that, but that will likely entail a near rebuild of my entire system, so I've been avoiding it, but, unfortunately, it's increasingly becoming more of an issue.

Agreed
