I was cleaning up my photo account and found this video I took for someone who wanted to see the Kohler Karbon in action. I thought I'd post it here in case anyone else is considering it.
I love the faucet - the look is perfect for my kitchen and overall, it's great functionally. I don't miss not having a separate sprayer at all, and I love the fact that I can fill pots, vases, pitchers, etc. on the countertop and "fix" the faucet into whatever position I need. On the con side, while it moves easily, it's not effortless/ballet-like as the Kohler videos would have you think. Also, I'm often turning the joystick with a wet hand, so inevitably, water drips down on the escutcheon. While it wipes off easily, water spots are quite noticeable because it's such a shiny and large escutcheon.
