I am using Nokia 820 for 3 months now. I wasn't sure about Windows Phone 8 at the beginning but I still give it a try as I like Nokia. To be honest after using almost all mobile systems (iOS, Android, blackberry etc) I think WP8 is quite good! OK there are still things need to be improved, like the "other" storage problem (which in Nokia's latest update has due with it but still not perfect) and the limitation of app storage (can only store in system memory, not on microSD), I think it's a good system, especially if u have friends and family members also using WP8 (I especially like the "Family Room" function).
