Ha. I experienced two decades of Bloomberg. It was always a melange of ancient Fortran tabbed forms with never-to-be-fixed bugs and newer consistent TUI. By 2010 they had started to pile on mouse menus.

The advantage was in typing a command and most of its arguments quickly.

I hope you didn't seriously associate the price $250 with Bloomberg training. Everything Bloomberg has a lot more zeroes after it, except what they pay to new hires in Princeton.
