From Macworld:
“The $69 Swiftpoint Mouse is a head-turner simply by virtue of its unusual design. It looks like no other portable mouse, and it operates differently, too. Whether this supersmall, distinctive mouse will work for you depends upon how large your hand is—and whether the position it forces you into feels comfortable to you.
The Swiftpoint measures about 2 inches long and about 1.5 inches at its widest point, toward the back. Intended for righties, it has a large, grippy groove meant to cushion your thumb, the left and right mouse buttons lined up in the middle section (with the right-click button raised more prominently than the left), and a more awkward cutout on the right to accommodate your index finger and (more critically) the scrollwheel.”
