I ride clipless on my road bike, cages on my fixed gear.

It's comparing apples and oranges. I'm glad that you found something you like, but I don't think this is some huge breakthrough. Everyone knows that clipless is superior in a lot of ways, but it's also very impractical. I bet all of those coffee/shopping/etc runs you do will add up and eventually you will just leave your cages on instead of always switching out pedals...that's what happened to me when I was using my road bike to commute
