Although its just a concept, i’m guessing that if this gadget hit’s the market it will be a success. Much of it success will depend on its price though, so if they manage to produce this keyboard at a reasonable price i will sure get one. Yes, its worth investing some money into a keyboard if you spend much time in from of one, because it will make your life better and easier.
The Optimus Tactus Keyboard has no physical keys, its just a display that can be configured the way you want it. For example you can have it display a color palette or you switch it to text mode and have your usual keys, or the coolest mode, you can switch it to video mode and display videos directly onto the keyboard. For the moment this is just a concept, not even a prototype so we cant expect it to be produced to soon, but who knows.
