It’s easy to forget what a difference multitouch capacitive touchscreens made to mobile devices. As far as I’m aware, the iPhone was the first device to use it at scale. Apple also spent years designing a new interaction paradigm for it, taking multitouch from cool tech demo (Fingerworks) to the mainstream.

Microsoft had Windows Mobile and WinCE for years before iOS, but typically they got the UI wrong and tried to jam a desktop interface on a mobile OS (a few years later they overcompensated and jammed a tablet interface on a desktop OS). By the time the iPhone was out it was too late to rework Mobile into a multitouch OS.

Famously, the BlackBerry guys thought it was impossible to put a full desktop os on a phone, and that Apple must have faked the initial demo. Again, by the time they could respond by ditching their existing software and buying QNX it was too late for them too.

Android only survived because it was a new OS and the team immediately ditched their Blackberry clone UI and built an iOS clone instead. Even then it took until at least v5 before it was as smooth as iOS, and the tablet story is still poor.
