Gizmodo notes TouchStream’s new MacNTouch Keyboard, a “revolutionary” add-in product for the 15-inch PowerBook G4. It “integrates the functions of a large-area super touchpad, a multi-hand, gesture input command station, and a ZeroForce keyboard, all on the same smooth surface. The MacNTouch’s non-mechanical ZeroForce keys require only the lightest touch, make no sound, and can be moved around to suit the needs of the individual user. Users of the MacNTouch Keyboard will never have to move their hands between the ZeroForce keys and the pointing device since the ‘mouse’ is always under their fingertips.” The US$259 keyboard will ship in July.
