A person that has an almost unhealthy obsession with gadgets, gizmos, and other personal electronic devices, including their internal components, new feature announcements, and new devices all-around. These items are often inseparable from the person, and the person claims (in many cases) that the devices are extensions of them.
"Man, brian's such a geek. His iPhone broke the other night and he hasn't even been able to function."
"What a gizmophile."
