Point. Click. Drink! MugMouse is a new mouse that holds coffee or tea so you have to move it more carefully than a normal mouse. This means you have to move the mouse really slow, especially if its filled with hot coffee. Talk about slowing down productivity! The mouse works like a mouse - you push down on the whole mug to click. The whole bottom section of the mug is a mouse button. The mouse connects to your PC via USB and can hold about 150 ML of your favorite drink.
