Completely different experience for me. Symbian was a confusing mess, so much that I stayed with a feature phone for another while. WP8 felt responsive, the UI consistent and surprisingly clean. Scrolling was smooth in 2013 when on Android it had frequent stuttering except maybe the flagship devices. The problem was that it was missing all the important apps and then some. They made sure to set the bar high for starting to develop apps for it and then wondered why nobody started porting to WP.

Nokia was in the process of switching from Symbian to Maemo, but Microsoft installed a Trojan of a Stephen Elop and forced the crap that is Windows Phone down Nokia's throat.
