Hotmail syndrome. I'm going to change mine to say "Sent from Google Glass" just for kicks. "This message transcribed from an awkwardly public soundbite"
I prefer "Sent from my phone". Why on earth would I advertise my particular brand of phone?
I changed mine to "Sent from my iPhone 6". People were wondering how I got one =).
I prefer "Sent from my rotary phone". No need for free advertisement or misplaced smugness about a disposable gizmo.
I might start using "Sent from my Pokedex" or "Sent from my Pip-Boy 3000"
