I am so not into this whole Optimums keyboard thing. They list all the feature and then never release the thing to the public - they just keep working on it. And plus, what normal user with $1500 to blow on gadgets even wants lcds on each key? Great, that keyboard will have a paintbrush for that tool in Photoshop, and my key will only say B, what it it has always said and I have known that was the brush tool shortcut for years.
I guess I don't get the point of this thing at all. If you check out this companies site, it is full of artsy stuff that is ultimately pointless and not being made anymore.
