Thank you for your reply. I agree that the graphical interface is core to general usage of the phone and I should have been more clear that I was talking about two sides; the daily driver and the dev side. App support and the ability to run apps (i.e. graphical interface) are of course necessary for a daily driver. However, my point is more of a stance in product and marketing, not any specific feature. I simply think that Linux devs are a large community that it might be possible to reach with a focused effort. One of those is a dev-focused keyboard. I know there have been attempts with keyboards by other parties and it is hard to do well (the memory of Planet Computers and the Astro Slide is particularly painful), but if marketed to devs I do believe there is an untapped market there. Provided you can get sufficient daily-driver stability, that is the kind of market where you can sell to companies that buy the phones for their employees. For any professional developer making code that runs on a live environment, having access to a development machine at all times is extremely valuable.
