I had Turbo Pascal and Turbo C. The compilers were insanely fast compared to what had come before. But I still think that programmer ergonomics sucked. There was no syntax highlighting, definitely no autocomplete, and it couldn't necessarily find all the syntax errors on the first pass, so you'd fix a few errors, recompile, and there'd be a new set of errors. That's my recollection anyway.
It was 1991's Turbo C++ 3.0 (they merged Turbo C and Turbo C++ with that product) that had syntax highlighting and code folding, so it wasn't the 80s :-). Hard to believe, but Turbo C came out in 1987 and was pretty primitive. I seem to remember the early version of Turbo C would just hard stop on the first syntax error. Fun times.
Borland introduced syntax highlight on Turbo Pascal 7 for MS-DOS, if memory serves me right, while all their products for OS/2 and Windows 3.x provided it from the start.
Autocomplete came around Borland C++ 4.0 timeframe, or something like that.
I don't think we knew what we were missing though. I just remember how fast it was and being amazed that it came with four inches of printed documentation.
