Just got a 950XL
I got a 950XL yesterday - My first Windows phone. I chose it, as I'm loving my new Surface Pro 4, and liked the idea of everything syncing seamlessly between the two.
I spent a large chunk of what should have been last night's play time watching the phone configure itself, then install updates and restart many times. I did a manual check for updates before bed, was happy that all were done, and left it on charge.
I got up this morning to find a message saying that another update required a reboot, and that I could either reboot now, or it would automatically do so in 3 hours. That reboot took almost 40 minutes!
I want to give this a go, but am so far not impressed.
