I'm about every 2 years. Started with a WinMo6 Samsung Omnia - Droid 1 - Galaxy Nexus - Note 3 I love my Note 3, but it's definitely starting to show its age. I HATE the design of the Note 5, so I'm looking for something new, although there hasn't been a "Killer App" to really make me jump from my Note 3. I've still got unlimited on Verizon, otherwise I'd just get a Nexus 6p and Proj Fi and call it done.
Still looking for that "Killer App" or revolution. Nothing on the horizon as far as I can see. IMO, with the removal of SD slots and removable batteries, we're moving backwards... (My WinMo Dell Axim had TWO card slots! SD and CF!)
