I absolutely love it. Bikes are a little annoying to stop and start; "walking" your bike for a short stretch requires physically dismounting. My scooter allows me to constantly transition between standing, walking, and riding as environmental conditions require.
Also... it's stupid, but if I have to wear a helmet to do something, I'm not going to do it. I can't imagine riding a bike without a helmet, because it would be too easy to hit a bump and fall over. On my scooter, however, I feel relatively safe without a helmet. There have been a couple times when I've lost control of my scooter for some reason or another, but because I'm basically standing, I've just kind of jumped off.
