But it's half funny and half sad that the biggest competitor to FoxPro in history was not Borland/Aston-Tate with dBASE, or Borland with Delphi, etc., it was actually Microsoft - with Access, VB, VS/.NET, and SQL Server.

I have a slightly different perspective. First, Fox had big competition in the early years - competition from Ashton-Tate, QuickSilver, and Clipper. It's just that Fox won the battles by producing a better product (while dBase IV and Clipper 5.0 were horrible failures, and QuickSilver just never evolved).

I never saw Fox as competition to SQL Server. SQL Server is a database platform. I understand the perspective of the history of MS and Fox and your blog posts, but I think some of the products you mentioned are more of apples-oranges comparisons.
