Apple has submitted a patent application for a flexible computer screen worn around the wrist.
So… an iWatch then?
While the application doesn't mean Apple is definitely making a wrist-mounted iPhone-style device, it's a good clue that there is more than a hint of truth in the rumours.
The device as described in the patent is a screen attached to a 'slap bracelet' (aka a bi-stable spring) which would fit any user.
The AMOLED screen would be designed to maximise battery life by turning off unused pixels, while powered by a "kinetic energy gathering component" like existing watches charged by walking.
Engadget notes that according to one description in the document the device would be able to read emails, act as a keyboard and browse music, which sounds about right given it's an iOS product.
