He might already be trapped
in the ecosystem and, despite having realized that there may be things he'd like to try on a different mobile platform, leaving that whole ecosystem behind would cause serious inconvenience.
Hell, even though my iPhone is the only Apple device I personally use, losing access to iMessage with all the people I know with iPhones (my wife most importantly; she is a 100% Apple convert) would be a real pain in my ass as I will not pay the highway robbery charges for text plans. And no, I cannot expect most of these people to start using Google Voice to text me should I decide to switch to another mobile OS, so that's out.
Combine that with the hassle of having to find replacements for my existing workflow and app usage patterns on some other mobile OS, and my answer is "why bother." I suspect for others it is a similar situation. When it comes to my workstations, I care enough to bother. My phone just needs to work when I pick it up and go away when I put it down, that's it.
