My MacBook is my work life. My phone is super important to me, but given some devil's choice, I'd go back to a StarTac before giving up the laptop!
My wife is the opposite. For her, in both professional and personal contexts, the computer is more like a screwdriver -- just another tool. The phone is where the computing happens, and you'd have to pry it out of her cold dead fingers.
Thanks for this. It summarizes succinctly my uneasy observations of large numbers of mobile users.
For desktop power users, however, the mobile is somewhat an extension of their desktop.
