What do these people call the huge problem of Blackberry/WinMobile/Tizen/etc stores and there real lack of meaningful applications? Those have become niche devices and got pretty irrelevant. Beside that even on iOS and especially Android (due to the bad inbuilt privacy control in <=5.1) many remove native apps like Facebook/Dropbox/Twitter/etc and rely on their web apps. Those run just as good and don't record the GPS, voice, upload photos and SMS, etc.
