Have's vs. Have Not's

Sent from my iPhone. Sent from my Blackberry. It isn't that people CAN'T edit their signatures. Parasitic passive plumage on pda's and iPhones offers consumers token prestige in exchange for cheap advertising. It is then up to the consumer to incorporate the vector fully into their lingo to further serve their master, announcing that they intend to 'iText' a message to a friend.

Maybe a tag-team combo of GPS, MRI brain scan, and twitter can send recipients even more passive information, offering the exact location, circumstance, and intent of the person sending the message. So it reads 'sent from my Blackberry, sitting on the can at the Circle K station, W. Blvd, on my way home from Cap'n D's.'
