>Corporates usually replace hardware every 3-4 years don't they?

Yes and no. 3-4 years from when the person got it maybe, which is usually not the manufacture date. And, it's one of those budget items that tends to get pushed out when there's a financial crisis, like now for many Covid affected businesses. I work for a F500, and my laptop was made in 2018, and is a 6th gen Intel.

At the companies I've worked for the programmers generally get new hardware about as often ...but other workers not so much. They are more likely to get the hand-me-down hardware.

Wow what a good corporation. We rolled windows 10 last month, hardware changes are very rare, maybe every 10 years. Usually done on a rolling when needed basis.

Laptops might be cycled that often but ah guarantee you many other machines are much MUCH older.
