"Sent from my iPod"

I got an email earlier and at the bottom it said "Sent from my iPod".

Is it there for status reasons or to excuse the crappy typing typical of such a device?

I am tempted to add a tag to my emails "Sent from a non-Mac, dowdy, boring ol' PC".

SISYPHUS ADDS FROM HIS iPHONE: My iPhone adds a "Sent from my iPhone" tag. I occasionally delete it if I think the recipient of my e-mail may be threatened by my uber-hipness. Usually though, I leave it so my correspondents will know that they are dealing with someone who is hip, savvy, and rich enough to sport the latest and greatest in technology. (And who just may have a shot at Drew Barrymore.)

In summary, I have an iPhone and JB does not.
