I got my device just over a week ago.
It must have been the last one of the official preorder period as the form was filled in on the last day of the preorder period but it was send a couple of hours after midnight (so the next day).
It was a long wait but man am I glad I got it.

Question 1:
Is there any chance to flash my device to sailfish using a laptop running windows10?

Question 2:
Does anybody know why the device won't stay OFF when it's connected to a charger?
