>but this will never be mainstream and this was implied in the question of the post (Will Linux phones become a viable alternative to the Android/iOS duopoly?)

The post goes into detail about the reason for the current duopoly is the difficulty in procuring modern SOCs with linux support, nothing to do with how said phones will be used.

And I don't really care about being able to bank on my phone, I would gladly buy a cheap android device for it if they stop you from being able to bank on desktop devices, I just need linux on phones because of how much android sucks for daily use and how annoying it is to do anything on it. If we do get the ability to run android on modern hardware, it stops being necessary to have a separate desktop/laptop as well, I could just use a dock, or just a keyboard and mouse instead, especially since the Macbook Neo has shown current mobile hardware is more than enough for "casual" desktop use.
