Apple Files for OLED Keyboard Patent
pegdhcp writes to mention that Apple has applied for a patent on a 'dynamically controlled keyboard' with OLED keys. This may seem remarkably familiar, since an OLED keyboard has been bandied about by Art Lebedev studios for quite a while now. "while the Optimus Maximus is a bit expensive, Apple could certainly mass-produce something similar for less money, perhaps bringing the price into reality for most users. Lebedev has, however, apparently applied for several patents for the Optimus, so it's unclear just what Apple is up to, or what would happen if the company were ever to release such a product."
What the Hell are you ranting about? The important question that the GP asked -- and which you thoroughly failed to answer -- was this: were displays (of any sort; it doesn't matter which) ever put into the keys of keyboards?!
