Isn't that too imprecise? And volatile? If your criteria were the "majority" of smart phones and tablets sold each year, well then that might change from year to year. As an analyst doing a report like this, you need to make a clear distinction -- even if it is a wrong one -- for the sake of clarity and consistency.
