I carry a Road Morph pump that works great.
One cartridge will fill my 700x32 tires to about 90 pounds. But I still carry a Zefal HPX frame pump, too, and seem to end up using it about two thirds of the time. I always use the pump to get a bit of air into the new tube before putting it into the tire, and I feel like re-seating the bead with the pump is less risky to the new tube.
One thing that's annoyed me lately is the number of spent CO2 cartridges I see lying in the bike lanes on my commute across town. Somehow, I doubt that those are being tossed there by BB gun users.
