This is one of those unique gadgets that first was a concept and everyone loved it so it became a real product that you have the possibility to buy online. Called the USB Typewriter, the device replicates the way people used a classic typewriter, but this time on a computer, iPad tablet or a smartphone.
The idea comes from Jack Zylkin and enables the look and feel of an old mechanic typewriter. It works as a keyboard that plugs into one of the USB ports of your system, supporting functions characteristic to keyboards, such as CTRL, ALT, ESC, and the arrow keys.
