Meh, I got into CMU SCS, and chose Tufts, because I was equally interested in comp sci and music, and Tufts had a much superior music program.

Early on in my career I'd get questioned about my CS degree from Tufts, and I'd jokingly mention "I'd gotten into CMU SCS, but I preferred to be a well rounded individual. I can send you the acceptance letter if you'd like."

I think people choose schools for all manner of reasons.
