The interfaces look like they wanted to be graphical, as they have windows and drop down menus, and they wanted to have multi-tasking, as they implemented the overlay tools in Borland Sidekick. They wanted those things but they were limited to staying in text mode because widespread adoption of any real graphical interface was slow.

It seems a little humorous now that professionals were stuck for several years doing their day to day word processing, spreadsheets and databases in text mode, where getting different sized text or different fonts was almost impossible. This also wasn't just in the 80s, it was still somewhat true in the early 90s, not very long before the beginning of the internet as we know it.

Still, I wonder if things are really any better now, as we're all using software interfaces built on something else that's not really appropriate for the job. HTML.
