Let's see... I miss... this old version of Ektachrome 64P, before they brightened all the colors to, actually, try and look more Kodachromey.
Vericolor II... (used to do weddings with this in a 6x7, very nice, especially for color negative film of the time. I haven't tried any of the newer color negative films that might be similar. )
Someone mentioned Pan-X... I was missing that recently, though it wasn't really a favorite at the time...
It's often been a thought of mine, that if we have to have digital, what if we could download emulators for these old films like ringtones?
