Pump fan here. Never used CO2 before, but don't see the need either. I've had a sum total of three flat tires in 3,000 miles of commuting year round. I don't mind taking an extra two minutes to actually pump up the tire. Besides, one of the reasons I bike is for exercise. A pump can be a decent arm workout!

As long as you get a pump from a reputable company. (+1 on the Topeaks). I once had a cheap Schwinn pump from Target I got for $8. It lasted two inflations before falling apart.
