Me? No... LOL
I was always obsessed because I always treated them like a toy instead of as a phone. Being anal (OCD) didn't help either, I would sell it because I dented and/or scratched it. Last year, not that I was happy with it but I sold my S4 3-4 weeks because it had a very tiny dent were the buyer couldn't even see it. LOL
One time I had two Note 2's (Black & White), I used the other as a 5.5" iPod or bought the M7 twice because I made a mistake selling it. I can't remember why I did but I know the second didn't last long either because I sold it for the Note 3.
This year I may break my personal record, I just don't see myself selling my S5 especially having spent over $100 on accessories which is the first ever.
