I can't stand riding upright. Sure, my butt is comfortable, but my body feels like a honking huge sail. Make that "anchor". So I'll gladly spend the money and time and testing it takes to find a saddle that will let me ride leaning forward. Moving as fast and efficiently as I can is one of the big kicks I personally get out of riding a road bike 
  We all get our kicks in different ways 
PS. I ride somewhat more upright on my mtb bike, and prefer it in city traffic at lower speeds and with more need for quick maneuvering.
