Why doesn’t a Windows smart phone become popular like Android?
One of the main reasons of Windows Mobile’s failure was lack of apps.
This was a chicken and egg problem: developers refused to make apps until there were more users, while users refused to use the platform until there were apps.
Eventually Microsoft saw that it was not worth it to continue pushing Windows Mobile, so they phased it out.
It really is hard to create a new mobile OS these days. Android is so strong, no one will really consider your new OS until there is ANY compelling reason for them to do so, which frankly Windows Mobile didn’t have.
