Since graduating from college in 1993, working in the graphic design industry full-time through 2019, I had two brand-new Macs (a PowerMac G3/800MHz, and a G5), the balance were hand-me-downs from other employees --- the G5 in particular was especially long-lasting, though ultimately it was supplemented by an Intel iMac.
Each year when Apple came out with new machines, we would make a game of putting together a dream machine --- ages ago, that could easily hit 6 figures, these days, well, a fully-configured Mac Studio is $14,099 and a Pro Display w/ stand and nano texture adds $6,998 or so.

Not surprising considering the CPU in the fastest "desktop" Mac before today was slower than an old Intel chips you can buy for ~$350 (e.g. the 14700k).
TBH, for non-tech folks that upgrade cycle has likely stretched a good bit beyond 3-5 years. 3-5 was the norm 10 years ago, but I’d wager needs-driven upgrades, opposed to marketing driven, are closer to 7-10 years outside of obvious niches.
Sample size one: My spouse is using either a 2013 MBA and wants to upgrade, mostly b/c the enshitification of web sites. Basic productivity was okay-ish for her work (document creation, pdfs, spreadsheets, etc), but even Gmail now suffers with more than a tab.
Edit: thinking more, I don’t know if I agree with myself here.
> 3) Apple support devices for longer than Android, that's nice!
> 4) God, why do their benchmarks compare devices that are 3-5y old?!
2 and 4 kind of contradict each other.
I wouldn't be surprised that the average upgrade cycle for a lot of folks is in that 3-5 year range, for both personal and corporate buyers.
