It was. That purchase spawned a career out of my evening hobby. Then, a few years later, when I was mostly using C or VB, and only firing up Pascal for fun now and then, Delphi came out. I was super excited. Until I realized I could barely use it, and none of my local book stores had anything on it that was helpful to read.
By the time the internet came along, and I got into full time development.. .net was out, with "academic" pricing for VS 2003. That purchase brought me real jobs, at real companies.
So, for me.. Borland got me curious, got me hooked, then I switched to tools that got me money. Maybe that's because the ecosystem had changed, but I can't be the only one.
