That's not a resistive screen, read up on their matrix screen technology. It may take more than one click, though. Either it's a resistive screen, like the N900 (and it can (not) be done in software) or it's not. Embedding a matrix inside changes the build and no longer makes it a resistive touchscreen. Since it is a technology that isn't quite resistive nor capacitive in behavior, I'll call it a hybrid (it does both). And we're all waiting for those. There is a lengthy thread on this issue already, complete with software implementation in pseudo. Now, let's get back to topic, k?
Here is how Stantum-type touch-panels are manufactured: 1. Two thin and transparent (glass or plastic) overlays are covered with conductive material 2. The material is patterned in rows on one side and columns on the other, transforming the layers into a matrix of conductive tracks. 3. The two layers are assembled superposed, the conductive sides facing each other and separated by a spacing material (transparent dots, air, etc.). When one or multiple touches occur on such touch-panel, the top layer slightly bends, thus creating contact between the two layers right below the touches. The controller chip detects the electrical contacts and determines the exact location of the touches.
Resistive touchscreens are composed of two flexible sheets coated with a resistive material and separated by an air gap or microdots. When contact is made to the surface of the touchscreen, the two sheets are pressed together, registering the precise location of the touch.
