no it will continue to grow as long as iSheople are allowed to breed. I have a few nephews that are 5 and 9. They both have their own ipad minis. A year or so ago I was on my android phone and the older one asked me if that was a iphone.. When I told him what I had he rolled his eyes like my phone was junk and he couldn't be bothered.
Both of their parents are iphone owners.
Just look at the buzz over the iphone 5.5" phone. They make it sound like there hasn't been 5.5" phones for the last few years..
