I do remember a few short yrs ago there were hardly any apps and the software was buggy as hell, slow- lagged all the time, wifi issues etc. All you heard than was Apple have so many apps etc.
It is also worth remembering that the only way to do things in Android or iOS is through apps or via limited mobile browsers. Even buggy and limited apps were better than nothing (unless you were content having just the basics phone/music/video/email/internet/maps). Therefor it was critical for Android and iOS to have app stores supplying apps. Obviously this is not the case with full blown computers where apps through an app store are a supplemental benefit and not an absolute requirement.
