Corel Corp seems to be making a success of Wordperfect in a way Novell Inc never could. Steve Ballmer, Microsoft Corp executive vice-president, sales and support, says Corel is selling the suite it has structured around Wordperfect and Quattro Pro to some computer manufacturers for under $10 a machine, forcing Microsoft to cut its prices much more than it would like. Corel puts more pressure on our revenue than any competitor we’ve got, Ballmer declares ruefully.
