Ok so I am not really keeping score BUT it seems to me the score is:
Apple 15 BILLION (apps downloaded)
Facebook 750 Million (users)
Let’s see if I remember this… carry the one, subtract out the value of Pi, hmmm divide by the circumference… ah yes then Multiply by 1 / e
YUP seems to clear to me… Apple wins by a factor of 20. Good luck Facebook.
