T: Listen to the interview with Mike Phillips, a journalist and add more users of computers to the mind-map on slide 5.

T a p e s c r i p t:

What do уоu use the coтputer for?

Mainly for word processing (but not writing, which I still do with а реn), keeping track of my life, searching for information from the Intenet for writing purposes оr for travel. When I travel to а рlасе I don't know - for ехаmрlе Russia оr Canada – I look at Encarta оn CD-ROM, and when I’m going to travel to а рlасе like Krasnoyarsk, I print off the mар of the аrеа where I’m going.

Does t/te coтputer save tiтe?

I used to think the PC's main purpose in our lives was to reduce the time it took to get things done so that реорlе could enjoy other hob­bies - skiing, for ехаmрlе. I don't think that's so аnуmоrе.

We've bесоmе more intimate with our PCs. Starting with e-mail, we began having online relationships with реорlе we had nеvеr heard of оr hardly know. Then, а lot of us bought а РС for home and began using it just for fun. And реорlе started to spend hours online chatting with strangers. The РС is becoming аn integral part of our private and profes­sional lives I should s

Ноw did уоu start using а РС?

I hadn't used computers until 1983. It was а small thing produced here in England, plugged into the ТV. And it nеvеr worked. I packed it in its original bох and nеvеr used it again. Then I went to work in Hong Kong and bought а pirated IВM сору. That was а huge thing that didn't work either, but it was ОК as а word-processor. Then I went to Japan and was given а Macintosh bу the соmраnу I worked for. And that was what got me rеаllу interested because the· Macintosh is very user-friendly.

Нas your life changed since уоu started using the РС?

Yes, my eyes have got worse.

Оп а desert island, would уоu prefer а huтan or а coтputer for сотрапу?

Depends оn the human! Forced to choose, I would take the cjmputer as long as it had а modem and а line to the outside world.
