They are nonbinding, PROVIDED THAT you apologize profusely in the event of reneging on your promise. I broached this very subject in the allopathic forum, because I too wrote a letter of intent to my first choice school. After I reflected on my primary criteria for choosing a medical school, I developed serious misgivings about my first choice school--in particular, I was worried about the price tag. Two physicians advised me to not think of the LOI as binding; one of them, in fact, wrote an LOI to a school, broke his promise, and ended up doing his residency at this school. He told me that he called up the school and explained his situation; in effect, the school wrote him a letter, refunded his deposit, and wished him the best of luck in his medical studies. In other words, his failure to follow through on a promise did NOT adversely impact his future.
The bottom line is that applicants can't see the future and they aren't all-knowing, wise creatures; thus, it is acceptable to change your mind regarding a school. Just make sure that you inform the school of your choice and the rationale behind it, and that you apologize for the ethical blunder. Don't sweat it, man. It's your future. You're a human being and human beings, by definition, are fallible. Admissions committees are composed of physicians who are acutely aware of what it means to be human, to NOT be perfect.
