Corel Corp intends to fight the overwhelming dominance of Microsoft Corp’s Office in the suites market by abandoning the idea of charging for each machine on which the suite is run, and instead offer a Windows NT server copy for a one-time $900 regardless of how many people may be attached to the server. Users would download elements as they needed them, and the company could use a similar approach on the Internet if it could work out an appropriate pricing model for it. It will shortly have a beta test version of a suite written in Java for use with the Personal Digital Assistant it plans for next year.
