7 years ago, we started a company called Collaxa. At that time, all our intranet servers and developer machines where dell/windows with a couple of linux machines only (CVS, build). Most people where using Office.

This year, we are starting a new venture. This time, all the developers run on Mac and all the servers are either hosted or running linux. All the presentations are make using Keynote, the intranet is a wiki (no more word) and some google spreadsheets. No one is using Office. The end result: we have not payed a single dollar to Microsoft.

Although big corporations are locked in, the trend is clear. MSFT is going to need a major turn around to get back on their feet.
