one of my pals who graduated last year went straight out into the buisness world manufacturing custom designed surgical instruments. I was also thinking of going this route and asked him basically the same question you asked.
He says that most buisness-persons are not even aware of the pre-med, med school, residency, fellowship, attending track. They are just impressed with the M.D. behind your name. Think about it... if you went up to your aunt Gladis and said "I'm a doctor", is she going to ask "where did you do your residency?".
Most MBA's don't care about residency because they aren't even aware of how people become practicing doc's. They only care about the M.D. behind your name. We will soon have arguably THE most prestigous degree available. Buisness folk eat this up, even if they don't understand it.
FYI, I am doing an intern year, so I can moonlight, but that's it.
