"Unix will continue to gain market share at the high end of the
server market at the expense of other systems, with demand
driven primarily by ecommerce and the increased use of handheld
devices to access corporate data."
"...enhancements to Unix at the high end such as the addition of
systems management software previously only available in the
mainframe world, is spurring organisations on to replace older
proprietary systems, according to Steve Josselyn, research director
at IDC's commercial systems and servers unit."
"As a result, while IBM's S/390 mainframe still has a 35 per
cent market share at the high end, with Unix trailing at only 17
per cent, Unix is likely to grow its share of the sector to 30 per
cent by 2003."
