Topeak alone has pages and pages of pump styles for sale. There are a lot of gimmicks offered. Just for fun I made this list, and this is just one brand:

• convertible presta / schraeder head (fortunately most of them do)
• pumps on both strokes
• switch to a smaller shaft / cylinder nested inside the main one when the pressure gets high
• various levels of material from all-plastic to all-aluminum to carbon-fiber
• has a little hose
• Has a little foot
• has a little pressure gauge
• has a little dial pressure gauge
• has a little digital pressure gauge
• hides in a seat post
• pump head doubles as CO2 inflator
• Has ends made to nock into frame corners
• any of these in different diameters and lengths and color

I am pretty sure I've seen one that has multiple telescopes like a pirate spyglass, but I don't see it from Topeak

The newest wrinkle is lithium battery electric pumps. I feel that these are booming and I'll probably try one soon.
