I'm concerned about the combination of size and resolution:

    Display: an LCD display that is 5.7″ at 720×1440 pixels

The size should be smaller, while the resolution should be probably higher.

They mention, that such resolution is caused by heat dissipation issues[1] (since they by design don't use integrated SoC). May be size is also caused by separate chips?

Regarding the browser, it would be nice to have something based on Servo, rather than Epiphany. Are there good mobile browsers that use Servo embedding and can work on normal Linux?

About a Servo based browser: I plan to get my in progress-but-really-unusable-so-far Servo based phone UI (https://github.com/fabricedesre/servonk) working on the Librem 5. But honestly it's frustrating to see how little general web compat work is happening in Servo right now, where most of the team effort is directed to VR/AR use cases. I'm not blaming the team, but it's hard to believe in Servo outside of niche use cases right now.
