Microsoft Exchange business is good

I was reading an article in The Microsoft Exchange Team Blog on the Release Candidate of Exchange 2010. Read here.

One interesting paragraph caught my attention.

According to a 2008 Ferris research report, Notes/Domino share has dwindled to a mere 10% in enterprises, while Exchange has grown to 65% market share across all organizations and continues to grow with more than 4.7M starting the switch to Exchange last year. In fact, Exchange is now is approaching $2B in annual revenues. If Exchange were a standalone business, it would be the 9th largest software company in the world. We expect that momentum to accelerate with Exchange 2010, the most compelling version yet.

Wow!
