I use my floor pump at home, much more frequently than I use my seatpost pump, or any other bike mounted pump that I have had.

As for a pump on the bike itself, I started with one that the Evil Empire sells, I think that it was a Bell. It got replaced with a Topeak Mountain Morph pump. I then decided that I liked the idea of my seatpost also being my pump. Now, I have a Biologic Seatpost pump. I still carry the Mountain Morph pump in one of my front panniers, mostly, to help others.

I roll with Schwalbe Marathon Plus tires, so I don't actually use a bike mounted pump often.
