To date, all of RIM's Blackberry devices have been notable for two reasons: Seamless integration with corporate email servers and their surprisingly useful but tiny hardware keyboards. The Storm continues Blackberry's tradition of email excellence, but it dispenses with the keyboard, opting instead for a large, iPhone-like touch screen. But it goes Apple one better by fixing some of the deficiencies of the iPhone screen. For starters, the Storm screen is backed by a grid of springs, so every screen press can respond with tactile feedback.
From a usability perspective, the Storm offers a better Web browser, which can sense lighter and firmer presses on the screen, allowing it to differentiate between clicks and cursor movements. This isn't possible on the iPhone.
