I don't know if I have any friends who miss carrying coins and cash, or who miss carrying individual bus/subway tickets, but if they do, they're awfully quiet about it compared to the friends who happily say they can't remember using cash.
I'd say that if anything, cashless things are catching up to the general public.
Personally, I'm in favor of keeping things cash-friendly because people shouldn't be forced to be cash-free, but that's only to support a small minority of people.
