Not a tech company, but I feel strongly about this when it comes to LAMY (a fountain pen company). As far as I can tell their pens (notably the Safari and 2000) have stayed almost exactly the same for the past 40 years!
The only thing they tweak in these pens are the limited edition colors, which for the Safari they're releasing probably 3+ per year. I once met a guy who had a collection of over 50 Safari pens so I guess that market works out for them…
