In other news, I've finally received shipping confirmation of direct-from-BA order #8xx (paid mid-November) which is an X1.
Me too !!!
I hope to have voltage control implemented, anyone have some news about this

X1 doesn't have hardware voltage control like X3, and they also don't display Watts and Volts on their web interface (or LCD).
There is some limited software voltage control through SSH, but only allowing you to step down the voltage, not increase it.
