GPRS is a key step on this path. A key enabler in itself. But that does not mean to say GPRS applications are simply a means to an end. Just because higher bandwidth becomes available, it doesn't mean everyone will use it. Some operators and end-users will not go any further down the mobile internet path than GPRS, probably because the bandwidth it provides is perfectly adequate for the kinds of applications they offer and want to use, respectively.
Cost is also an issue.
GPRS applications look set to be very cost-efficient for subscribers and operators alike. For subscribers, GPRS allows charging on the basis of actual data transmitted rather than connection time. For operators, as packet-data technology, GPRS only uses network resources and bandwidth when data is actually transmitted. Because the market for GPRS applications will be there and most likely remain there when 3G arrives, the applications will need to be of high quality and value so that people will want to use them and continue to use them. There will be no single 'killer application' for GPRS only killer portfolios.
