Sony VGP-UMS50 mouse goes wireless, adds joystick

sony mouseSomeone at Sony really must dig this thing, because the company has actually put out a wireless version of its oddly-shaped, non-ergonomic VGP-UMS50 mouse. In addition to making it wireless, Sony's put a joystick on top instead of a scroll wheel. Makes sense, since this is now being pitched as a remote for presenters instead of a desktop pointer, which makes this potentially a lot more useful than its wired sibling.
