If you started on SQL Anywhere, SAP, you were pretty deep in Enterprise sauce so MSSQL make sense.

And "Holy crap, this is not cheap" is why I see plenty of companies transitioning off MSSQL.

We started with SQL Anywhere way before it was SAP. SAP was the primary driver to move away, but it also fits nicely with our customers, some which want to run their own MSSQL instance.
