Taking apart the Storm 2 reveals how the new SurePress works
So does the Storm 2 use this Piezo technology discussed on the new video? It is not certain, but some of that technology might be involved in the process where the screen does not move when the power to the phone is off, and returns to the clicking mode when the power is restored. Cutting open the phones does show that the Storm 2 does not have a button for each letter, number and function key under the glass. It seems that simply putting one button in each corner and removing the one in the middle better reproduces the feel of typing on a physical keyboard and also allows the user to press down on two different letters at the same time for multi-touch capabilities. No matter how RIM has improved SurePress, if the keyboard lives up to its promise, the Canadian manufacturer will have achieved its goal of making a virtual keyboard feel like a physical QWERTY.
