Arbitrary huh...
My two long term pet peeves for which I would be most happy to help lobby to get them a hearing:
1) Faster than light travel 2) Create a robot that carries it's own power supply, communication device, and webcams that would allow me to traipse up and down any path in Rocky Mountain National Park in real time so that I can take a hike for 20 minutes when I need a break without the requisite plane travel and hotel bill
I suspect pg would be willing to pay for at least number 1 :-)
