Electrical engineer. Probably something involving radio since I focused on Communications when getting my EE degree. After college I went to work for a company that made industrial computer I/O interfaces and then got into embedded programming instead.
Musician.
Soometimes, while playing guitar, i wish i would not own a computer, because i'm sure my guitarplaying would be so much better... then i snap back to the real world and am happy as fuck that the computer pays my food.
I guess it depends on what you'd consider a "computer", but I'd probably be into radio engineering and electronics, what I was into as a kid, before home computers were around.
Sometimes, I still feel like I want to go back to it.
