I agree with grawk (is his name Dan? I'm going to try and refer to people by their first name) on his take about Comp Sci. Programming is rarely fun, and the last time I found it fun was programming for a startup that interested me. Those jobs are rare, and I'm currently programming for a small finance company here in Manhattan. It's boring, but it pays the bills.
But if you're interested in it, then I say go for it. Study a few years of it and have some fun. When you get your degree and you still enjoy it, give it a crack and see where it takes you. If you know for a fact you dont' want to do it for a living, there are many options in the finance world that a CS degree can take you. A CS degree basically shows your competant in logic and your mathematical skills are top notch. I know plenty of CS/Engineers who took the quatitative analyst/developer route and make a good living.
But hey, what do I know, I'm 24. =T
