I didn't read all the replies cuz it seems like some folks were getting butthurt, so I'll just add my .02
I epilate my legs because I like it. Everything is smooth, it's easy to wipe off grime and since I also mountain bike, easier to clean scrapes and cuts. I like the looks too as my leg hair grows in all weird so removing it all is favorable. Speed? Well I'm not that fast to be worried about that little bit of time.
