Given that remote attestation already had deleterious effects for user freedoms on smartphones and tablets (meaning, choose between banking apps and any deviation from the factory ROM), Pluton should be seen as a danger.
If you want a general purpose computer get a laptop.
Most likely one sold by Linux OEMs, like Tuxedo and System76.
A de-Googled Android or iOS device with a judicious selection of apps is good enough to fulfill 80% of the "geek device" use case segment (though not at the same time - de-Googled Android is better at running arbitrary software, whereas iOS seems to be better at painless privacy). I'm just not invested enough in open smartphones to fight PinePhone's software immaturity, or to spend crazy amounts of cash on a Librem.
On the other hand, I was an adopter of the Pinebook, and will be for (affordable) productivity VR as soon as I get the chance. For both of these form factors, I'm more than happy to write 80% of the UI I use if it gives me what I want otherwise.
