> I played with Windows Phone 7 and 8 (not tried 10).
Used all three, still use WP 10 (Lumia 650). The 8.1 was the best, 10 feels like a downgrade, except for the Edge browser that still mostly works on web sites (the IE in 8 was hopeless, but one could replace it with Opera Mini).
Paradoxically WP is less of a spy than Android, and more secure (mainly due to less users to write malware for). I never thought I might say this of a Microsoft product! So that is one reason I have kept it. There is a Samsung S5 Neo in my drawer waiting (hand-me-down from my son, who gets the new gear these days), one of these days I will join the Android Borg collective...
