Jeffrey Mincey has a look at the customer base for the Mac and Apple Watch.
Apple says the Mac has a customer base of about 100-million users. iPhone pushes nearly to 1-billion. iPad is perhaps nearing 250-million. What about Watch? Those who track such things use math to make guesstimates, but noted analyst Horace Dediu thinks the Watch customer base is over 40-million. Not bad for a three year run, huh?
