I bought this phone in 2012 and then exchanged it with lumia 630.
I liked the touch senstivity in its display. It is just amazing, I can use it with wearing winter gloves too. I dont think this feature was present in any other phone.
Pictures from its back camera are also great. For me the colour saturation in photos was perfect.
From the start I liked the User Interface of windows mobile os, the ui of photos and store app was the best.
Again navigation was one of the best, with gps and glonass and here maps navigation exprience was always wonderdful.
I remember my friends with android device envy my phone for navigation and photos.
The only major con is lack of apps in windows store.
