I thought everyone knows that pie charts are bad graphics. Humans are very poor at comparing angles, which is what you need to do when you compare slices of the pie. 3D pie charts are the worst, because you introduce an additional useless dimension into your display. With a 3D pie chart, you’re displaying one-dimensional data in three dimensions, which is not a good thing to do.

So I was surprised to see this picture of so-called master of design, Steve Jobs, giving his latest Macworld presentation (via Engadget):

Anyway, the new Macbook Air looks cool, but it’s too expensive. And you can’t replace the battery yourself. That seems kind of annoying, because in my experience laptop batteries only last about one year before they start to wear out.

In spite of his using 3D pie charts, you do have to admire Steve though. What other CEO can get people to camp out overnight waiting for him to make a presentation of new products?
