I’ve said several times that I loved my Ubuntu phone. But we parted company shortly before Canonical abandoned Convergence, along with further updates or support. 

Since then, a couple of less ambitious ventures have set out to bring Linux to the smartphone. Sadly, nothing close to mainstream. 

It now seems that Samsung have a plan to achieve a workable compromise. An Android device which can be switched over to Linux when connected to a monitor and keyboard. Fingers crossed.
