I gave up on Windows phones about 8 months ago. Sold them all (except for one 1520) and first bought a used iPhone 6 Plus. Sold that and got a used 6s plus. Very nice.
Now I have 3 iPads, the 6s plus and an 8 plus is coming tomorrow. The integration is awesome, the apps are welcome, and everything just works fine. Typing this on a 10.5" iPad Pro. Best tablets available.
Windows phone is basically just a bad memory now. There is literally nothing that I miss. At this point I don't understand why I clung to WP as long as I did. Like many others here, I just had an irrational hatred of Apple.
Just let go of your hate, and come over the dark side. That's what I did, and I could not be happier.
Yes, I tried Android first. S7 Edge. While the phone itself (hardware) is awesome, Android 7 is just an ugly mess. If you liked Windows 98, you will love Android. I mean, an app to kill apps that you closed 2 days ago (because they are draining the battery STILL), and to clean the memory? Really? This stuff was all automatic on WP, and is all automatic on iOS.
