Most of the time when I'm busy working on my computer, I will have a can of Coke or other soft drink to accompany me. And it sucks big time when I leave it beside my computer for awhile and it's not cold anymore. So I'm very happy to find out today that there is this USB Mini Fridge that will keep my beverage chilled beside my computer. It holds only one can and it is powered by USB - no batteries needed! Yay!!
