Also read another source that was hinting that Apple was possibly not the first to come up with such a device - there was the hint that it was invented by someone else - patent infringement, etc. Well, if true Apple has walked down that path before - they ripped off the Tony keyboard...remember?
If it is Apple's own invention, I really question how a changing color computer would contribute to the computing power of an Apple system. It seems like all flash with no substance.
Bingo.
The core group of Apple users will think it's cool, though...the effete, snotty artiste types which Apple has to play to in order to survive.
There's a group like this in the PC world but the industry largely ignores them.
