I have a cutesy Roll-Up USB Keyboard.

One of the facts in life which I find fun, is the existence of some technology that did not exist, when I was first getting started with computers. One example is in a USB Keyboard, which we can simply roll up. But one needs to be slightly careful with this one, because if we actually fold it, it may become creased! :) In fact, this one has a crease, but still works.
