Microsoft courts mainframe shops, pushes Windows use - Computerworld: "Some mainframe users were ripe to make a change, though. For example, Glen MacGregor, assistant vice president of business systems at Lombard Canada Ltd. in Toronto, said the firm's IT department proposed replacing its IBM mainframe at budget time last year.
