3) Touch Screen Provides Tactile Feedback

One longstanding complaint about the iPhone's touch screen is its --in other words, the screen offers no response when you hit a key, making it difficult to type without staring directly at the screen.

RIM listened to the frustrated iPhone users when it developed the Storm's keyboard, which uses "Click Through" technology to provide both audible and tactile feedback whenever you click the screen. In fact, is really just one large button that actually depresses when you click it.

, and though the device I experimented with was a preproduction unit and the software was buggy, it was easy to see how the small amount of feedback the new screen provides could potentially improve typing efficiency.
