We've had this discussion before, but I absolutely 100% disagree with this. Give two weeks notice, finish up your immediate responsibilities, and leave things in good order. People quit all the time with 2 weeks notice and don't burn bridges.
I know lots of people that were immediately fired upon tendering their resignation (2 weeks notice.) It has happened to me personally. Why give up that extra pay by quitting early and taking that risk. How companies react is going to depend upon what industry you are in, and the specific company that you work for, but I, personally, wouldn't take that chance.
Be as honest as possible when quitting -- butter them up by saying how it was great working for them and that your quitting has nothing to do with the company, people, etc, but instead with following your dreams, etc. Quitting a job with people that have been good to you is always difficult, but you're just moving on.
