Why Most Touchscreens Miss the Point
You’re not crazy, and neither are we: The touchscreen on the Apple iPhone really is more responsive than the screens on the BlackBerry Storm, the Motorola Droid, the Nexus One and many other phones, even though all of these devices use essentially the same touch-sensing hardware.
Though handset makers buy their touchscreens as components from the same select pool of suppliers, a good touchscreen experience requires more than just hardware. It requires a bit of design alchemy blending software, engineering and calibration for the perfect feel. Few smartphone makers have managed to get that balance right, say experts.
