lumia 620 was my first smartphone. before I didn't have preference in phones I just used whatever I could get my hands on, always loved nokia though I owned more nokia than any other brand. I actually first knew about windows phone when the lumia 920 was announced and said that had to be mine. I owned the 620 first then 920 which is now in need of a new logic board and now I am rocking a lumia 1520. I still thing the 920 is the best lumia ever IMO, if I could get that phone with today's specs I would be happy. and like you I am never leaving windows phone
