Call it UMTS, WAP, GPRS or whatever. Young people don't care that much about technology - just about what they can do with it. And what they want to do is to stay in touch with each other. I believe we will see an explosion of different services on the mobile networks. However, I do not believe the most fancy ones will necessarily become the most popular.
Social interaction is very important to young people.
In the near future, you will be able to send photos and video clips via your mobile. Johnsen believes this is a service young people will adopt immediately. A phone call is in itself a rather cold medium. People don't see each other. You are just a disembodied voice.
