I can't speak for the user you replied to but I can speak for myself: they stopped making good devices. I had a lumia 920, then I upgraded to the 930 which I still consider one of the best phones I've ever had, for its time. Then MS just... stopped. Took them forever to come out with the 950 and it was nowhere near competitive both in hardware quality and design with the ios and android competition. That was the last. Everything was awesome until after the 930 they simply stopped coming out with competitive devices for me.

Roughly at the time the 950 came out I switched to androidland. This year I wanted my upgrade to be the iphone but when the rumours about the lack of headphone port became undeniable I ended up by upgrading into a new android phone, which I'm using right now.

All of this sucks because there's absolutely nothing that comes close to the fantastic design and usability patterns of windows phone.

I left Windows Phone because of the hardware. I couldn't stand the capacitive buttons anymore, so I switched to an iPhone since it was the only flagship phone without capacitive system buttons. There is nothing that replaces Windows Phone live tiles though. The closest you can get is widgets but it's not even close to the same. There's no Twitter widget on iOS, for example. And the widget section is a completely different UI.

I took a major step back in UX because of poor hardware designs. I shouldn't be forced out of an app just because my finger slid a little bit off the screen and hit the home button.
