Sony Ericsson K800i. No, I'm not kidding. I always carry around my laptop and/or my tablet (which has no SIM support), so I only need a phone in my pocket to check the time (I don't like carrying anything on my wrist), send SMS and call people (people in my area are usually responding to those more quickly than on Skype, Facebook, Viber or whatever).
