If you're interested in something of an even higher degree of robustness and are fine with an ARM device, check out the MNT Reform Next: https://www.crowdsupply.com/mnt/mnt-reform-next

I really wish we could get an MNT device with upstream support, if not an x86 processor. Having used the Pocket Reform, I think about it quite often. It's almost perfect.... but the ARM chip and all the warts that come with SoC crap basically is the one single thing that keeps me from using one.
