Ok, I just got my galaxy note 3 dual sim a week ago... sold my s4 and added a few bucks. I must say, I'm really really happy with it. I've read this thread prior to buying but, well, it didnt convince me "not" to buy another samsung phone.
The dual sim, the external memory, the removal battery, the high-ppi-screen, the deep blacks, the s-pen, and a whole lot more, are some of the things that I just couldnt live without nowadays in a smartphone.
Current Phone: Samsung Galaxy Note 3 N9002 - rooted for perfection
