Common people don't care about the OS, they care about apps.
It's a chicken-egg issue. The last 10% of polish won't be done till a critical mass of users adopt the platform, and vice versa.
Remote Attestation and the Play Integrity API will soon make that stop.
My statement is based on 25 year as an IT professional where I migrated people and businesses from Windows to Linux, from iOS to Android, from old Unixes to Windows/Linux and the list goes on.
Just give to people the apps they need or want and the rest is easily managed.
