I still remember the Lumia 920 as the best phone I ever used.

Snappy, well done OS, intuitive, great camera.

What Microsoft mobile lacked, despite having a higher market share than iOS at some point was app support.

Developers and companies pretended it did not exist.

Banks, your local transport, whatever.

I think that was what killed windows mobile phone.

Any other just doesn't hold: os and hardware were very, very good.
