The data raises a question with me. The 'pie' is not finite.New customers join the equation. Existing customers upgrade from choice or necessity. Some users hop the fence to another manufacturer.
Question being, what is the longevity of ownership/usability? Do loyal users of one type device purchase three upgrades while the loyal user of another maintains the same device?
What is an average length of ownership before replacement becomes necessary?
Just wonderin'. The one set of numbers doesn't seem to relay the Big Picture.
