The Lazypad Mouse Replacement
If you work long hours in front of your PC and may find using the mouse for a long period of time quite uncomfortable, a new device may alleviate your distress. The Lazypad from Noahpad is a mouse replacement that is a combination of a touchpad, a mouse and a numeric keypad. Tapping and sliding within the pad moves the cursor position on the screen. The left and right click action on the conventional mouse is also represented on the pad. Dragging is achieved by pressing and then sliding within the pad. This device is connected via USB and a Bluetooth version is also available. Source: noahpad.com
