Once properly patched (and that's a 3 minute job if you know how to do it), they're as good as new.

I've always found patching a tube on the road to be a real pain. Also, the tube of glue in my patch kit always seems to dry up before I get to use it. Time is money. I with the "toss it" camp. It is better to throw in a new tube and finish the ride.
