Time for more biased opinions :-)

I did my undergrad at The Ohio State University, which provides some contrast to dragonchild's Ripon College, since OSU is either the largest or one of the largest universities in the country (depending on the servey in a given year). I majored in Chemical Engineering, so I can't speak directly to what the CS program is like, but I did want to address what is implied in dragonchild's post: personal attention and small schools. Yes, there are around 50,000 students at OSU, but all of the professors in the ChemE department knew me by name and where always willing to talk, give advice or help, or whatever. So try not to hold a school's size against it.

There are also considerable advantages to going to a big school. There is always something to do, no matter what it is you like doing. I could go into detail, but just use your imagination instead. Also, there tend to be more resources at a big school; at OSU for instance, there is one of four government funded super computer centers.

I did my graduate work at the University of California, San Diego, where coincidentally, is one of the other super computer centers. I continued my work in Chemical Engineering, though since I was doing a lot of modeling, I wrote several thousand lines of code (though if it was rerendered in perl, it would no doubt be several hundred lines of code :-) The CS department is part of the Engineering school, so I occationally had contact with the CS undergrads, but not enough to form any real option. If it weren't for UCSD's location, I would fully recommend OSU over UCSD for computer science; but if that sun and ocean thing are for you, UCSD can't be beat (execpt possibly by UCSB, but that is beside the point).

Hope that helps,
Scott
