At the mortgage company I worked at after college, the entire company was using "command line style" "ms-dos" looking software that ran the entire company. This software completely dominates the entire mortgage market! Makes some boring ass mortgage software with a GUI and some bug fixes and you might make yourself a millionaire. And the software was not "rock solid". It had all kinds of bugs that screwed up customers accounts and cost them $$$. The only reason companies use shit like that is because it beats running the company manually without a computer. So anyway, go out there and write yourself some boring business process software!
