Abacuses: They were great when they were useful, but the advent of calculating has made these devices quite obsolete. They are a small board with at least 25 to 40 beads connected onto about one dozen wooden strings. The board can be used to solve thousands of problems, but there's still one problem they can't solve, even with the largest and most complex human brains---blankets with sleeves. People said about as recently as 25 years ago that 2012 would have flying cars and robots performing dangerous labor. But we've got blankets with sleeves. Now, that's the dumbest idea in the history of modern history. It's also one of those ASOT products, witch suck so bad!
