I rode with schrader valves for quite a while, even drilling out the rim. I argued that the schrader was just fine, and for the most part it is.

Right now both of my bikes have presta valves. They are actually a little better valves for bicycles. Not night and day, but better.

Back then I used my air compressor to blow up my tires. Now that I have a really good floor pump (Joe Blow Sport) that's not really an issue; I can pump my tires up in less time than it takes to plug in the compressor and let it build up enough pressure. I don't bother with adapters anymore, I just have the proper pump in the first place.
