Hardware will become a commodity while software and service will account for a greater share of computer companies' revenue, say market watchers. And growth in sales of special systems will come to a halt in the '90s. As more computer systems are based on such emerging standards as the Unix operating system, customers can pick and choose the best components from different vendors rather than relying on one supplier for complete computer systems. That will accelerate demand for service--rather than products--from vendors. It's the service, the support and the software that add all the value. The move to distributed computers linked by local area networks is increasingly becoming an alternative to centralized computers. A survey of 50 Fortune 1000 companies found that 72 per cent were replacing their minicomputers with personal computer networks. Some trends in the peripherals (外部设备) arena in the next decade are obvious--smaller, quicker, more features. But manufacturers of monitors, printers and disk drives will be looking beyond the computer industry toward future markets that hold vast sales potential. The automobile industry, for example, holds promise for peripherals vendors. It's very likely in the next five to ten years we'll see vehicles targeted at business executives with printers and fax (传真) machine capabilities built in.
