Off topic note here: Apple forecasts a "logarithmic leap". I have never heard that term. Logarithmic growth is sub linear and doesn't seem like something akin to a leap. Usually you would go with "exponential". Just seemed like odd wording.
Logarithmic growth is a more accurate description of the actual growth and on a limited interval grows faster than linearly.
It's symbolic of the typical winner-take-all markets in the IT sphere, unlike the term exponential, which is constantly misused and inaccurate in most cases (except, perhaps, for Moore's law on a limited time interval)
