New Apple Patents for Possible Mac Tablet

It seems today that there is more and more evidence that the fabled Mac tablet will eventually become a reality. Judging from these patent pictures, cameras will be able to track your hands and fingers where the keypad could transform into a gesture based control pad without even touching any keys. It could also be combined with force sensors so a computer will be able to tell how much more volume it should apply to a song depending on how fast or hard you do the gesture. Voice commands can also be used through the built-in microphone. Apple has some great ideas and I think they could really take this concept far.
