The Nokia N9's Harmattan platform was discontinued immediately after the N9 was released and when it was time for a new phone, I decided to go for a Nokia Lumia running #WindowsPhone. I had bought my son a Lumia 710 with #WindowsPhone7 and I was impressed. I owned both an 800- and a 900-series Nokia Lumia with #WindowsPhone8 before they discontinued the concept. It was a really nice OS experience, but it lacked a solid software ecosystem.
