I just read over at the AppleInsider that Apple has applied to the FCC for two new devices using Bluetooth, one is a keyboard and the other is a new mouse design.
But what I found odd is this statement:
The new hardware, people familiar with the matter have said, will do away with the mechanical roller ball and use an expanded touch sensitive housing.
This must be in error since mice have been ‘ball less’ for a long, long, time.
Maybe an Apple person can clear this up.
