I may even have to consider an iThing as my next phone...
Personally dual-SIM has been my absolute bedrock requirement for a long time; I've had the same personal phone number for donkey's years and have neither any interest in changing it, nor in allowing my employer access to it.
So I have two numbers; one for work and one for personal. Up to now that's meant dual-sim Android (most recently a MotoG6 which is a pretty decent phone), but also means I'm out of step with a lot of family and friends who have iThings and do stuff like iCloud photo sharing.
Assuming that Truphone or someone eventually has a UK voice offering and a way to port-in a number I could finally join the herd.
Or not, of course :)
