Much Better! Not only a Ubuntu logo in keyboard. Make Better! Create a Unique (or more than once) layout for the Ubuntu Keyboard.
I have an idea separately:
For people that need to write in more than one language, make a keyboard that's make possible change the characters (mini LCDs in all keys) by a program. And change not only the map-software, but the map-hardware too. Than you can write in English, Russian, German, Japanese, Korean, and so on... Make a basic (or expansive/modular) keyboard for this.
