Sadly there is no RemindMe for ycombinator, but yes I believe "far less" is still my conclusion here. I didn't quantify far less and I'm not sure exactly how much it means? Thirty percent less? Fifty percent less? Not sure but yes I expect it'll be more than a 5 to 10% haircut you cited. And more importantly - profits will be far less if Uber adopts a taxi-like model of supplying the hardware and charging drivers a use fee.
