There are a lot of devices that let you mouse around and there are a lot of devices that let you move the mouse pointer without needing a table surface. But it's a tough job finding pointing devices that act as both without sacrificing some basic functionality.

The RocketMouse is worth a close look. After all, comfort and usability are personal things.

The first thing that makes the RocketMouse stand out from other mice is that you hook your index finger through it. Its ergonomic design lets the body of the RocketMouse rest comfortably in your hand with your thumb resting over its small trackball. Two additional buttons can be pressed by your thumb as well. Your index finger also rests over the main mouse button.

You can move the cursor with your thumb and press the mouse button with your index finger with virtually no movement other than the pressing action. And since the index finger opening goes completely through the top of the mouse, you can use it right- or left-handed. The RocketMouse is ideal for laptops and presentations where no table surface is available. The 5-foot cord may be a bit short but any USB extension cable will work just fine.

The USB RocketMouse works with both PC and Macintosh computers. $29.95. 877-925-6778. www.rocketmouse.com
