I don't know if MS took out Borland, or Linux took out Borland. Maybe Borland took out Borland.
All I know is that for a sample of 1, me, I used to use (and really like) the Borland (Pascal, C, ...) compilers in the late 80s and early 90s. Then, I started doing more unix and then Linux work. GCC, perl and later Java was there. By the time Delphi was there, it was too late - Java had already provided a free equivalent. (Java is just Modula + OOP + UCSD-P-code in C++ clothing)
