It doesn't matter to them how many apps Android or Apple had after their first three months. All they know is two platforms have a lot more applications available than the new kid does NOW.

If a new credit card appeared but was only accepted in three stores, would you switch to it? "Hey, MasterCard was only accepted in two stores after their first three months!" "So what? It's accepted everywhere now."

I agree with those who feel the number of available applications isn't as good an indicator of OS quality as the quality of those apps. However, most consumers aren't developers.
