Sent From My iPhone

I have a bit of a dilemma.  How do you feel about people that have the tag "sent from my iPhone" on e-mail messages that were sent from their iPhones?

It comes as the default setting on the iPhone but now I'm starting to think it's a bit pretentious.

Comedian Mike Birbiglia recently said on Twitter, "Sent from my iphone" is the new "my other car is a Porsche."

Here's some other stuff he "tweeted" about the iPhone.

"Sent from my iphone" = "I'd like to have a brief, impersonal chat. Also, i have more money than you."

"Sent from my AT&T Blackberry" = "I'd like to be a douche-bag but I can't afford it."

& 

"Sent from my iphone" is a way of saying, "We both have access to computers but yours is in a public library somewhere."

So what do you think?  Am I being too self-important by keeping that on all of my outgoing messages?  It's not like I can't change it.  Should there even be a phrase like it and if so, what?

Tell me what you think in the comment area below.

Thanks for reading!
