Meaning of "in computers"

Please read:

A: Do you want to share a taxi?
B: Oh sure.
A: Are you here on vacation?
B: No, business. I’m in computers.
A: Oh, me too. I work for ABM.
B: Really. I work for Apple.

What is the meaning of “in computers” and “really”.




I think both of them was trying to convey that they were

working in Information Technology…

Hi Khahn

“I work in computers” means “I work for a company that is in the computer industry” (in this case Apple).

“Really.” (without a question mark): In the context I’d understand this to basically mean “I see.”
