Coming from dumb phones and feature phones to low-end android, L820 (3 years) and L640 (90€, used that now for 8 months). I'm also experimenting with 40€ low-end android as a work phone. Disclaimer: I have tried W10M many times and always reverted back to WP8.1.
- I like the start screen UI, lock screen weather and glance. Vertical scrolling is better than side-by-side screens. Even if transition has fancy animation

Start screen can be pretty much replicated with SquareHome 2. Next lock screen vs WP lock screen - WP still wins
- I liked social integration of WP8.0. WP Facebook is decent, but android version is better.
- L640 is very OK phone. It works a lot better than android with 8GB flash because apps, that can be moved to SD, go fully to the SD. And there are not tone of Google apps having second version (factory + update) of them. My experiment has just 0.5G/4G, but it runs Here maps etc fine. Pokemon Go is more like no go though

- I don't switch phones for fun and I don't jump on first possible device in sight

- I don't like how Samsung puts the controls. Back on right, WTF

I have used Apple products like 2 days. Not my cup of tea. Also both are expensive for their spec and their value of usage.
- I had hope for Windows on a phone, UWP etc, development to catch momentum, bridges, not so much on Continuum, but hey - my phone does not have it. I had hope for midrange device with good value (L830 never was) as an upgrade this year or bit later. Well, we all know how that went with MS ending consumer phone development and no serious alternatives in sight. Just enterprise and SD21x phones. Windows mobile is not dead. It's just pining for the fjords

- L950 is currently selling at 300€, but it is not interesting. Camera may be very good (is it on level with launch time marketing material?). Still - no.
- Last time I went to W10M and reverted, few apps were gone from the store. Guess if they are available at the other 2 ecosystems

- SMSes are stored in cloud and in that sense hard reset or device change is less painfull. I guess android still needs some app to store and recover SMSes. But then Health did not store steps to cloud even though synchronization was on. Health is also quite slow. Androids phones seem to have similar functionality.
WP8.1 is still nice OS to use, but for me, without devices or app upgrade path on W10M, there will be time to move over. Maybe I'll see what Nokia brand has to offer
