Windows Phone was super lightweight, got out of the way & wasn't obsessed with capturing my attention the way modern iOS & Android are.
My Lumia 930 was peak smartphone.
I don't want my OS to try and push me into platform vendor ecosystems. Most of the "clever" stuff in the OSes is of no use to me so I opt out where I can. Easier on Android than iOS.
Once there's a decent halfway attractive Linux alternative I'll switch to that.
