Teh iPhone Causes Typos?

Okay, I was right, and I was wrong.

The iPhone isn't significantly slower than other types of keyboards to type on, but it does cause significantly more errors.

An article at ITworld outlines the results of a study into speed and accuracy for different input methods. iPhone users made over twice as many errors (5.6 per message vs. 2.4 for a numeric only keypad).

Apple made a bet on an experimental user interface. Many of those aspects worked well (multi-touch is going to be a de-facto standard over time). Some of them, (the keyboard) didn't work so well.

I know that Steve Jobs hates buttons, but should his jihad continue to the detriment of his users?
