I miss:
Cadbury's Secret
Newspapers with 'news' in them
The days when being famous or a 'celebrity' meant you had actually done something worthwhile often over the course of many years to eventually be granted that status.
Decent television programs on a Saturday and Sunday night where the only celebrity you saw was the guest professional darts player on the charity game on Bullseye.
You can't beat a bit of Bully...
ITV regions, their idents and proper locally made broadcasting, about the only thing that survives on that corporate plastic monster ITV now is Fred Dineage!
Windows 3.1
Common sense...
Politicians who were not in it for the money they could trouser off the gravy train
Buses that worked (Bristol VR's, Leyland National's, Atlanteans, anything bodied by ECW, well maybe not the B51 coach...) rather than the nasty over engineered plastic we have today that has to be replaced after just three years thanks to overbearing DDA and TfL requirements.
Loco hauled cross country train services that could respond to demand just by adding more coaches, how simple!!
Decent children's telly, Loony Tunes cartoons, Tom & Jerry, all now all but banned by political correctness!!!
