I was surprised to learned we have had more than 450,000 customer and partner downloads of the SQL Server 2008 Community Technology Previews (CTPs) across the globe. There has also been more than 75 large-scale applications already in production with more than 1350 applications being developed by nearly 1000 independent software vendors!
