Just in case you think the above image is a joke, you would be very wrong. It actually works and is available to buy now. It also works for PCs and Macs.
"This antique typewriter has been modified to work as a USB Keyboard for PC, Mac, or even iPad! That's right -- its a beautiful and fully functional computer keyboard!
The USB Typewriter can type all letters, numerals, and punctuation marks. It also includes shift, space, and return carriage (which is literally activated by the typewriter's return carriage!). Many non-standard keys, such as F1-F12, esc, ctrl, and so on are available with a special toggle key.
The modification is very clean leaves the typewriter looking, feeling, and working like a regular typewriter. You can use it as your primary computer keyboard, or turn off your monitor altogether and type on paper while saving your work to disk. You can also use it as a convenient keyboard dock for your iPad or other tablet. A beautiful, functional, unique addition to your home office."
