I guess you never took Nuclear & Particle and had to type the SEMF into a calculator :) I have my TI-89 Titanium next to me on my desk as I speak. I used it a lot in Applied Physics. I used it during thermo, I used it during optics lab, I used it during electronics exams, I occasionally it during Linear Algebra, I used it during Physical Chemistry. I used it a lot during undergraduate lab. I didn't use it in senior year Classical or E&M. Sometimes I used my laptop (when I finally bought one 2 years in) for those things, but I'd end up remotely logging into another computer on campus and punching stuff in Maple when that was the case. It was a speed thing. It's faster (and more explicit) than a scientific calculator, and accurate for what it is.
