All of mine have them, though it took until some time this summer. I suspect all the majors have rolled out chip cards - it's to their advantage since they can dump liability on vendors once they have a chip card out there.
Around here, probably 2/3 of the places I regularly use cards at read the chip. I have yet to see a gas station that takes it, though. Most of the chip readers are very annoyingly slow - a few have gotten dramatically better, but not most.
On another note ... when I was in Europe a few weeks back, I used my chip card - which I carefully get a pin for. Pretty much no one asked for the pin - the card readers all spit back a "get signature" to the vendor.
