Flutterby™! :

Lloyd Wood's Jaundiced Eye thus far has interesting notes from talks by Eric Raymond and Don Norman, both worth reading. From the Don Norman one:

And, speaking of gear-shifting: when he talked about how easy a car was to drive, he contrasted the complex car with the simple unicycle, which is far more basic in construction but is much harder to master.

This comparison gave pause for thought. 'Easy to drive' may be true for US automatics, on wide, straight US roads, but here in the UK we have driving lessons, narrow roads, and gears. Oh, and roundabouts; you know, traffic circles. Nothing much happens if you fall off a unicycle, whereas cars do annoying things like explode if you steer them into concrete walls at speed.
