Thanks merkhet.

How this might be measured:

What percentage of buyers in past Q1s were new users.

What is the difference between that number and 50%.

Assuming number of old users buying Macs holds steady, use that
difference to find hypothetical sales growth.

This is not the only angle to take on this - I remember reading reports
on Mac PC market growth, that were largely ignored.
