We have a snowblower attached to our tractor to do the driveway, and a walk behind one to do the walkways. I had to shovel the deck, that was more than enough work for me. It was about 4"-6" deep depending on where you were except for the 3ft snow drif that massed right up at the side of the house. I am an athletic person and that was more than enough work for me. I don't see how people can shovel their driveways unless they don't get any snow or have unlimited time and energy to waste shoveling all day.
I am fine with heated driveways, if thats what you want to spend your money on then fine. My neighbors that have it have it because their driveway as very steep and would be dangerous to do with a snow blower. Additionally, the original owners of the house had a Lincoln LS (RWD) and when they didn't turn it on, it was fun to watch the guy try to get up his driveway. We have heated floors in our mudroom, one of our 1/2 baths, and my parents bathroom.
