M: Good afternoon, madam. I'm doing some market research and I'm hoping you might have a few minutes to answer some questions.
W: Okay, sure.
M: Great, thank you very much. First of all, do you own a personal computer?
W: Of course! Doesn't everyone?
M; How long have you owned it?
W: I bought this particular computer last year. But I got my first PC in 1995.
M: I see. And what do you primarily use your computer for?
W: Well, I use it to send e-mails a lot, and... um, I have a teach-yourself French program. And I shop online pretty often.
M: Mmm. Any other uses?
W: Keeping track of my bank account, and there are a couple of computer games I enjoy.
M: Now you've mentioned e-mail and online shopping. Do you use the Internet for any other purposes?
W: Not really. I haven't got around to explore it too much.
M: Okay, thanks. Sorry to have given you so much trouble. Thanks again.
