MOTO Development has posted results of a DIY touchscreen analysis for the iPhone, Droid, Droid Eris, and Nexus One.

Using a simple technique that anyone can perform at home, MOTO evaluated the resolution and accuracy of each touchscreen device. All they used was a basic drawing program, a steady hand, and a few straight lines drawn very slowly on the screen.

"The iPhone's touch sensor showed the most linear tracking with the least amount of stair-stepping. The Droid Eris and Nexus One tied for second with only faint wiggling but actually performed best at the edge of the screen. Last in the line-up was the Motorola Droid, which demonstrated significant wavy artifacts or stair-stepping.”

You can take a look at how the tests were performed in the video below. A chart of the results can also be found below.

They are testing capacitive screens. The N900 is resistive. They could test Leo HD2 though..

This experiment guy shouldn't be too bias. I'm just a guy who knows nothing about this but i can try to speculate a different theory which challenges the word "Accurately" on the title. Maybe the droid screens are SOOOO accurate that it picks up EVERYTHING our finger touches thats MAYBE why the other phones seem to make jagged lines. And of course we all know that humans aren't perfect so there really no way you just made a straight line like that in the read world. Have you ever looked at a hand-drawn line with a magnifying glass? if so, please try using a microscope... then try an electro-scanning microscope... notice how your hand written line becomes more and more crooked as you look closer? Just some food for thought.
