“Sent from my phone” annoyance

Why should anyone care if the email they get is “Sent from my phone” or not. Does it add anything of value? I don’t think so…

Doubly annoying is that when people get emails on their mobiles, the urge to hit reply is too much to resist, so you typically get this:

Sent from my phone.

Look – just leave it!  Would you write some a letter or call them just to say  one word?!
