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.
