overall response about the screen is much better than the one on the original.

The BlackBerry Storm2's enhanced SurePress technology addresses the issues of the BlackBerry Storm's original SurePress design:

* Consistent Pressure - Because the screen is now sitting on four evenly spaced ‘buttons' (for lack of a better word), the amount of pressure required to create a click is consistent regardless of where you press.
* Multi-press capabilities - The improved SurePress hardware allows you to click on more than one part of the screen at a time. Taking advantage of this, RIM has allowed the software to now register two inputs on the keyboard. This is extremely beneficial when typing on the full qwerty keyboard in landscape. When typing letters across the keyboard from each (you are alternating between your left and right thumbs), you can now execute these letters more quickly as you can press the next letter without waiting for the screen to finish rebounding from the previous letter. It's more like typing on a physical full qwerty smartphone.
* Smoother Rebound - Clicking in and out on the BlackBerry Storm2's display is simply much smoother now, thanks again to the four electric button design. Use it side by side with the Storm and you'll immediately feel the difference.
* Face Detection feature! - Last, but certainly not least, the BlackBerry Storm2 features a proximity sensor that powers down the display when the phone is next to your ear on a call. Earlier hardware/software versions we have seen of the Storm2 never possessed this feature, but this review unit certainly does. Simply start talking with the BlackBerry Storm2 against your ear and the screen powers down - no more ear typing! As soon as you pull the phone away from your ear the screen powers on and you can enable calling features (mute, speakerphone, etc.). Finally!!
