Ha! The first time I did root locus diagrams in Linear Systems (or whatever the course was called), we did everything by hand and I hated it. 10 years after graduation I was in a certificate class for Mechatronics and we had Matlab. The difference was night and day. Suddenly I could play with root locations and see the effect immediately without having to do half an hour of tedious hand calculation. It's amazing how much your attitude improves when the work becomes "fun."
