I’ve possibly been a bit slow on the uptake, but I now foresee a problem in a couple of years time where Windows forces the latest features onto creaky old laptops making them unusable before their time.
Where we would/could have hung onto Windows XP/Vista/7/8 indefinitely (albeit insecurely) people will either have to move to Linux or (probably more likely) bin their laptop.
With my conspiracy hat on… Has an planned side-effect of the free Windows 10 been a ruse to revive flagging PC sales of recent years (Where MS make money from PC manufacturers from licensing)?
EDIT: For the record – I hate having forced updates. While it may make sense for most novice/every-day users, I personally find it a right pain in the arse.
