Speaking of these companies that run their Exchange servers without upgrading for 10 years...

If they recently upgraded to SBS 2011, they really have nothing to complain about until 2022.

If they're currently running SBS 2003 and are planning to upgrade in the next couple of years, they'll still be able to acquire SBS 2011 in the next couple years. Why would they even care that SBS 2011 won't be the "latest and greatest" two years from now? They went 10-12 years running SBS 2003 after all.
