Great example. While the calculator is a great invention, it's also caused many people over two generations of not being able to perform simple arithmetic in their head. Of course, we're hackers and we try to keep our minds fresh by doing simple tricks such as calculating the total value on the receipt before checkout (or the ubiquitous 35% off stickers a certain Dutch supermarket has)--don't we ;) And almost nobody knows how to use a slide rule any more.

And while that's sad, it doesn't make the calculator less great.
