I used Delphi for more tan 10 years, so this is what I believe it went wrong: * They lost Anders Hejlsberg * Free compilers got aceptable. * Lack of back compatibility, new VCL components from one version weren't compatible with older ones, every new versión require to biy the new components. * To expensive. * No new books to learn Delphi, they are to old. I'm still using Delphi 7 for some projects.
Bad sign.
