I had a 2003 Honda ST1300 (Pan) with ABS. It saved my bacon once. I don't feel it is a dumbing down of the riding experience, it is an enhancement, especially for a bike/rider that puts down a lot of mileage.
ABS is virtually "invisible" until you need it in a panic situation. If any rider thinks that they are better without ABS brakes on the street environment, they are fooling themselves.
I would love to have ABS on my Scura or Daytona. Since I don't, I ride very conservatively. Okay, I rode my Honda a little on the hot side and damn near had to pick up a nasty tab. But the ABS kept me out of a collision that happened in front of me. My ABS Panic stop hauled my ass down 6 feet from being involved.
Do you need it? That's a personal question. Is it for everybody? Maybe not. I for one, would embrace the technology and install the system if it were ever made available (not likely).
