seaninbuaa,
I realize the "wow factor" of Cornell but OSU has one of the largest alumni networks, especially in engineering. I've lived and worked all over the country, in a variety of industries and positions (all engineering related), and I constantly run into OSU alumni. Many of the alumni actively recruit from their alma mater as well. Conversely, I've only met one Cornell grad in my experience. If I were in your position, the choice for me would come down to whether I want to pursue a career in academia (Cornell) or be a practicing engineer (OSU), but that's just my opinion on the matter.
Good luck!
