I've never ridden one, but one observation I've made is that a few people I know who have decided to use them for transportation from, say, the train or bus to work have gotten hurt in some way by falling. One ended up with a broken arm. It could have been a lack of experience, but nevertheless, the first thing to think about is safety. It does not matter how fun or practical a scooter is if you end up hurt.
Edit:
To be clear, I'm taking about the unmotorized scooters.
