Check this out ..
Apple has sold 122 million Mac computers in the past 28 years.
Apple has sold 316 million IOSs ("I" devices ..Iphones, Ipods, etc) in the past few years. [ 150M of those devices were sold in 2011 alone]
Add them together that makes approx 440 Million devices.
The rumored Apple license was around $10Million with half going to PTSC..... so you can figure out how much PTSC received for each device
To my knowledge PTSC will receive nothing for anything sold in the future.
corrections welcome
