I'd rather trade Windows 10 for MacOS than my 950XL for an iPhone
Windows Phone is simply a superior user experience.
I'm still using my 950XL and my 1020 which is still the best camera on a phone (or is that the best phone on a camera). And I will until Outlook stops working.
Oddly the Guardian app and Shazam both stopped working some time ago but earlier this year I had to get a replacement 950XL (surprisingly cheap for a new one) and they both installed and work fine. Instagram will let me create a new account and use it but it won't let me log into an existing account which I view as spite. Waze claims it can't find a network - wait! there are two to chose from! - and gives up. But, against all odds on many levels, the little app for Dropcam cameras that I bought years ago still works perfectly.
After that, it's the lesser of two evils but I can't figure out which is which.
