Puncher:
XP embedded is everywhere - your life (and certainly your money) may even depend upon it. Some medical systems, widespread use in Industrial automation, POS, ATM's, among others, all use XP embedded.
While you may be right here, please do not confuse B2B with B2C products here ... if give an option, I would never go for a product that relies on XP embedded --- but don't kill me here: I am strictly speaking for myself!
Completely your choice and I would never argue otherwise............... what I would say is if all detractors (and we have a good few) managed to avoid XP altogether, in all its incarnations, they may well find themselves living in a cave😁
