The phones themselves were very good. I have a functional Windows phone in a drawer, that I sometimes charge (and it still works!), but after playing with the tile UI for few minutes... eww
Absolutely LOVED the tiles UI and so did everyone I know that gave Windows phone a shot. By far the best mobile experience I've had outside of a few apps I wanted missing. I really miss the OS. I think in general though the other commenters were correct that there was already too much market share coming from iOS and Android.
I absolutely loved the tiles interface and held onto my Windows phone for as long as I could. I eventually had to switch to Android when apps I depended stopped working on Windows phone.
