I know this thread is no longer that active, but I had a thought. The Purism group (main site) is a group that is focused on privacy-based, high-end hardware. They use Linux as a baseline OS for software privacy. While I personally think that they are a bit fringe/niche as far as their market and message, one thing they do make inroads in is higher-end hardware getting Linux support.
Given some of the other threads expressing interest in this, if Canonical does not respond, they may potentially be worth reaching out to. In fact, they recently announced that they would be wanting to create their own 2-in-1, and may be willing to work with Eve in some capacity (improving any of native N-Trig support in Linux, touchscreen input, keyboard use, etc) in exchange for recommendations on their own design process, introductions to some of Eve's manufacturing partners, or even a potential partnership to design their device? Not sure where things could go, but given some of the overlaps as far as goals go currently, this may be an interesting avenue to pursue. Their current campaign for the Librem 11 is on Indiegogo and on their own site
It does appear they are already in the process of shipping a product, so this may not be that viable any longer. But if they decide to create a sequel in the future, or perhaps explore improved hardware support, etc, they may still be willing to collaborate. It may also be completely unrealistic too, but i figured it may be worth looking in to.
