I disagree. I rarely use my rear brake on any bike, and I don't use it hard, either. The point about slipping in the wet is a fair one, and there are times when I will favor the rear brake over the front, but they are rare. That's because I ride on streets and roads mostly. When I'm on gravel and in a turn, for example, I'll favor the rear. I don't ride often when there is snow or slush on the ground, so I would be OK with crappy rear brake, but if you think you'll ride a lot on slippery surfaces, then you'll want a rear brake that works well.
