To follow up in agreement (and because I dunno how to make a new post),
I'm currently using a Samsung Galaxy J3. I hate Samsung phones, so why am I doing this?
I've always been a Zune fan, which is why I still foam at the mouth over WP7. It just has the hub experience, focus on typography, and stinking awesome animations that make me love the platform. It's customizable, more so than iPhone, but it's also indestructible and almost never crashes. Sure, it was lacking features, but it was a brick inside and out, never crashing for no reason. I loved it.
Then my Lumia 920 came in, which I loved too, but not in quite the same way. A few features that I loved were slowly going away, but I enjoyed everything the new platform brought. It was still the best phone for me, and I used it every day until I accidentally fried it (long story for another day).
Next was my 635, running 8.1. Don't get me wrong, tiles with background and Cortana were both features I showed off to my friends, but... I could tell something was missing.
Then I got a 640 and updated to Windows 10, and I discovered what I was missing. Sure, it was nice. The bigger app store, the shared app case and experience... It was nice. But after Microsoft stopped fixing big bugs in a timely fashion and stopped adding important features, it felt like a gimmick. Plus, I was sick and tired of not being able to use many apps that I wanted to (I even wrote emails to several companies, begging for WP apps. They were all answered... but they said no).
So what did I do? I bought a Blackberry Passport.
Yes.
I became a Blackberry user.
And I still would be if it wasn't for me accidentally breaking the battery and voiding my warranty.
I have a thing for voiding warranties.
Anyway, so I needed a new phone and fast, and I decided to do something crazy. I bought the same phone as two of my friends, the Samsung Galaxy J3. And yes, I felt like a traitor. And yes, it was hideous and I've changed every aspect of the design to fit my needs.
Here's the point of this article: the discovered something on Android. There was a Zune theme, and my heart (and the rest of me) did a happy dance. Plus, I hate to admit it, but Google Now on tap was... better than Cortana. Better search results aside, it was fast, stable, responsive, and context sensitive to my page, something that Microsoft hasn't got around to doing yet and won't for a while.
Oh, and Microsoft's apps are over here. Unfortunately, the good versions, too.
Currently, Android is more like WP7 than Windows 10 Mobile is. Microsoft has a bad habit of making good ideas, letting other companies do them first (and better), and when they finally get around to doing them, they're underpowered, buggy, and have no user base, so they move on and Google makes the victory.
As of right now, there's no reason to go back. Don't get me wrong, I love Windows Mobile, but unless they can get themselves together and make Continuum happen realistically... and maybe add a physical keyboard... I'm not coming back any time soon.
Oh, and then there's the app gap.
