P.S. Mike, I used to feel like you until my recent conversion to presta. If you haven't tried 'em, give 'em a try; you might just change your mind! 
O.K., guys, I am willing to listen. Is there really an advantage to Presta valves?
Yes, I have used Presta valves, but I still don't see the advantage - for people living in the non-Presta valve world of the USA. Of course, in Europe, Asia, Africa. Hmm, maybe everywhere besides the USA, Presta fitted pumps are easy to come by, but in the USA, if your Presta fitted pump fails, or if you lose it, or whatever, you are screwed until you find a bike shop or another rare biker with a Presta valve pump.
Oh, I suppose the valve is easier to repair - if you have the parts you need, simple though they are.
Granted, I am not using really high pressure tires, which may be a Presta valve advantage.
Is it the weight advantage? How much weight could you save? More weight than a good haircut would get you?
Seriously, what's the digs on Presta valves?
