Windows mobile can die as far as I'm concerned. I switched from the Lumia 950 to the Pixel 2 a few days ago and I'm very happy with it. Just moved my photos from one drive to google photos even though I think one drive is far better. I would rather have the built in support and compatibility to access all of my photos from years back on my phone and that was hard to achieve with one drive, not every app can easily access your one drive cloud. Google Photos is surprisingly fast accessing the photos in the cloud from my phone, maybe its the service or maybe its the phone. Now I can get rid of my monthly bill for one drive and groove. I hate to do it but I think I'm going to ditch office 365 next, I just like being on one platform.
The Pixel 2 has its shortcomings but overall it is twice the phone the lumia is.
