PostmarketOS fills the plaything niche like the Librium 5 and pinephone do but much cheaper with much better old hardware. Aside from a checkmark of running the latest kernel and hardware switches what can the librem 5 do an Android phone can't do much better? They aren't good phones.
Can you name any good real world uses?
Why on earth do you need two separate devices (phone and laptop), when you can use one for both use cases (phone with convergence)? No synchronization or double-backups and maintenance required. Also, decreasing the amount of e-waste is a good thing as well as fighting with the user-restricting duopoly.
It looks like for you Linux itself is also just for tinkering, since you can already do everything with Windows and MacOS, isn't it?
