Pick a d.me

In d.evolution many of the characters have computer implants that allow them to interact with holographic digital assistants called d.me (digital me).
Jason Smith’s d.me is a four hundred pound gorilla called Biff who gets around in a business suit. Charlie Mossman’s d.me looks like something out of Thundercats and answers to the name Ding Dong. An earlier draft of the novel had Louisa interacting with a digital assistant that looked liked Batfink‘s trusted companion Karate (unfortunately neither Batfink nor Karate made it into the final draft).

What if you could have a d.me? Who or what would you choose as your d.me?
