As a mostly contact wearer who still owns a pair of glasses (three or four prescriptions out of date, but not that far off really) ... keep the contacts.
It's less hassle having to dig for your reading glasses in the purse (or jersey pocket) where they always live, than it is ALWAYS keeping track of your distance glasses, since that's the only issue you actually raised.
It s*cks trying to operate a vehicle on public roadways without any peripheral vision, for the answer you didn't ask about. That's the reason I got contacts to begin with, and I'll stick with them unless I'm physically unable to wear them any more.
For that same reason, I'm really not interested in monovision or trying bifocal contacts. When I'm driving, or riding with or without a motor, I want to be able to see everything in my theoretical field of vision.
