I am a minimalist and carry few gadgets. My only current personal devices are a Macbook Air and a Blackberry Curve.
I've tried the iPhone 3G and although it's a remarkable device, the lack of a tactile keyboard makes it less than ideal for my daily high volume of email.
Although I have not yet tested the Blackberry Storm (the Verizon/Vodaphone model should arrive in my office for testing in a few weeks), I am impressed by the design which includes a tactile touch screen.
What's a tactile touch screen?
The user distinctly feels the screen being pressed and released with a gentle "click," similar to the feeling of a key on a physical keyboard or a button on a mouse. The "clickable" touch-screen, which Blackberry calls ClickThrough, gives the user positive confirmation that they have made a selection and the result is an enhanced touch interface and a more intuitive typing experience. ClickThrough lets you depress any portion of the screen to make a selection so it feels like there�s actually a button below your finger, thanks to mechanical switch suspension below the surface of the display that lets each press feel like a separate button, even though the entire screen moves as though it is one large button.
The Storm contains an accelerometer and when the device is tilted horizontally, a full keyboard appears rather than then tiny compressed keyboard of the iPhone or the "cell phone-like" SureType keyboard of the BlackBerry Pearl. The fact that Blackberry Storm enables a full sized keyboard in horizontal mode with tactile feedback could make the touch screen usable for high volume email users.
I'll report back as soon as I test it, but the idea of a touch screen Blackberry with a full size tactile keyboard is cool!
