Can send you a jolla+hwkbd for a tryout, XWayland is already running if you plan to interact just with keys (mouse/touch input needs work still afaik), closest to n900 it gets until neo, though that still is/will be on ageing libc/glibc/younameit so newer things won't work. If the things you need for work can be waylanized it's the way to go, if closed... n900 is still king prolly
