Totally agree.. as a recent (may 08) graduate, college didn't feel very productive in terms of starting a company but I do think I had the time of my life. I tried to spend most of my time enjoying the experience of having so many great people around me and soaking up the myriad of information from my classes. While I didn't end up starting a prosperous business in undergrad life, I did network like crazy and tried to learn a few skills to help me in my career choice (entrepreneurship).

That's one thing I don't think I regret or would tell my younger self to change. Don't get too caught up in work to miss out on the incredible experience that is college!

Yeah, I agree there. You should only start a startup in college if you can't help it.

the thing is that in those 4 years you can take it slow. You don't have the added stress of running out of money to pay for rent etc.

1-2 hours per day on a startup in college is no big deal. You have so much free time in college, that you can easily fit in doing a startup, going to class and having a decent social life.
