Activated by pulling out a grenade-like pin and palming an embedded fingerpad, the Armstar BodyGuard 9XI-HD01 sparks a loud and visible arc of electricity between its wrist-mounted taser spikes, a sight that inventor David Brown hopes will encourage would-be crooks to surrender.
We didn't have to change our usual or "traditional" finger positioning, meaning we were able to keep our right thumb in the bottom left corner of the pad and use our index finger to navigate. (Even if our thumb moved slightly up on the pad it still worked.) Best of all, while using that finger positioning we rarely zoomed in on something by mistake.
As for the keyboard dock's built-in trackpad, it responds surprisingly well to two-finger scrolls, but the pad's tiny size means you won't actually have much space to pull off those kinds of gestures.
