I know. I felt so damn cool buzzing around in that thing, and yet practically it doesn't quite meet my needs.

I could adjust what I "need," for example, I bet most walking people don't go faster than 5 mph (8 kph) to get across the street.

I edited my post to add in my sub-optimal experience when traveling over grooved surfaces, but they're not that frequent.

How often do I sit underneath a table? Pretty often.

What I'm surest of is the Apple-like lure. It's shiny! It's smart! It (almost) just works!
