FYI - and perhaps straying back vaguely towards on-topic - is
this open technology "laptop" project:

https://www.crowdsupply.com/kosagi/novena-open-laptop

This is not yet a durable road-warrior device, but perhaps it can
evolve towards an excellent platform for experimental lab hardware. 
It won't run x86 code like the compiled SL distro, but source can
be recompiled, and the modular design can accept a substitute low
power x86 board using and Intel Atom or AMD Geode.

Just in case, I'm stashing some surplus keyboards with trackpoint.
