A fantastic point in an editorial by Jason Snell for iMore:

There are plenty of other examples of Apple’s corporate culture and accepting the inevitability of change. I admire the way the company introduced the iPad with no fear about the possibility that it would cannibalize Mac sales. This was a lesson I learned during the early days of the web, when I was working for media companies focused on print: If you resist change out of fear that you’ll cannibalize your existing business, all you’ll be doing is allowing someone else to cannibalize your business instead of doing it yourself.
