I'm in college, and I've been applying around/searching for internships. I received an internship offer from a "big" company, but I'm not the best negotiator and was given a deadline of next week.

What should I do? I would prefer more time to go through the interviews with other companies. In http://www.joelonsoftware.com/items/2008/11/26.html, Joel suggests to "accept the exploding offer at the last minute, but go to the other interviews anyway". Is this ethical? Is it reasonable?
