Contrary to conventional wisdom, mainframe computing is growing.

Decisions about computer platform choices and options typically are made without consideration of true business impact from a cost-of-goods or other perspective. As a consequence of what we know about technology economics today, however, platform choices can be based on factual criteria and should not be decided as a "fashion statement."
