RIM today at last released the BlackBerry Storm2, its second touchscreen phone. The new model has a sleeker design that centers on a much-improved 480x360 touchscreen; rather than slow down users by actually moving the screen inwards, it uses a piezoelectric system that replicates physical feedback but still allows two-finger input. It's also the first Storm to have Wi-Fi and is much faster through carrying twice as much memory as the original.
