I've been making progress on a Computer Science degree for a while now, and have been working as an intern-level programmer for the last couple years. I'll be graduating in May and going to work for Cisco. Background over, I can tell you that, in my (albeit limited) experience, you don't need virtually ANY math to work in software. If that's what you're into, you can forget differential equations. Equations in general, for that matter. If your goal is to get a job and work as a programmer / sysadmin / IT guy, leave the math behind.

If you want to be an actual computer *scientist*, though, things might be different. There's a lot of math in the theory of computers, and that's something I can't speak to very well. If you're looking to stay in academia, or make a career out of research, you'll need your math. I'm not sure if you need a lot of differential equations in general, but theory is very math heavy. Industry == know about computers, and a tiny bit about math. Theory == know about math, and maybe a tiny bit about computers.
