"Delphi was more of a niche product, loved by independent developers but less prominent in corporate IT departments."
I had a client who'd used Delphi 6 for in-house projects. Just before I left they switched to C# for a new project. The size of the team started growing...and growing...and kept growing. I dread to think what the difference in productivity must have been although maybe their self-styled architect might have had a bearing on that.
