Sure, your USB ports support mice, keyboards, flash drives, hard drives, digital cameras, and other seemingly-useful devices. However, what if you brought a cup of hot coffee or cool milk next to your computer and left it for awhile while programming, surfing the net, or playing an online game? Beverages can easily become too cold or too hot.

Finally you can do something truly useful (grin) with a free USB port - attach a beverage warmer and cooler to keep hot drinks hot and cool drinks cool. No longer must you throw away a half-empty cup because the drink temperature does not meet your desired tastes. Thus, this small investment may actually save you money! (jk)
