At the end of the day, do you really care about Android users/iOS users? Does anyone really, truly care about this?
I would say this should be the concern but I also suppose people want to feel they made the "right choice" whether it be religion, political figures... Apple/Android products. *shrug*
Business care. This will tell them where to put their development and marketing resource. If business come mainly from IOS user, they will spend more time catering to IOS user through better app development, focus their market research on IOS user etc. This is an interesting article on app revenue comparison between IOS and Android.

Munster figures Apple owns about 85 to 90 percent of current mobile app spending. While hes measuring lifetime revenue, which provides Apple with an advantage, the discrepancy is larger than be explained by the App Stores head start alone.
With numbers like that, iOS device owners have nothing to fear when it comes to the possibility of developers fleeing en masse to Android as it becomes the worlds dominant mobile operating system. And it looks like Apple will retain that crown for a long time, too, even if trends continue to favor Android: Munster suggests Apple will keep more than 70 percent of mobile app revenue share for the next three or four years.
Why? Android apps just dont make anywhere near as much money through Googles Market, nor are they downloaded as often. By Munsters calculations, the Android Market has around 6,750,000,000 downloads to date, compared to Apples 18,566,331,811. Those have resulted in respective gross revenues of $341,765,335 and $4,939,611,127 respectively. Of the gross revenue, developers have seen $239,235,734 from the Market, while $3,457,727,789 has been paid out to those making software for iOS. Percentage-wise, paid apps account for only 1.3 percent of Android apps, vs 13.5 percent for iOS.
The difference is striking, and will mean Apples platform is likely to continue to hold a strong lead over Googles when it comes to the breadth and depth of software selection. It also means Apple isnt likely to freak out if Google moves a few more devices per year than it does; a strong ecosystem should keep customers coming back in strong enough numbers to keep iOS device and software revenue extremely high despite dwindling market share.
