Do not bring notes to an interview. It will make the interview incredibly awkward and not put you in your best possible light. Plus, I would have serious doubts of admitting a person to a world class program who would not remember and organize his/her thoughts and be able to articulate them.
I interviewed well over 2000 candidates while I was on admissions at Wharton and people did come with some strange ways of trying to make a point and none of them worked out very well. One guy I remember did have notes but they were written on his hand. There were also a lot of people who could not answer the question without continually referring to their resume. The worst offenders were the people who did not answer the questions I was asking but just articulated the information that they thought was most compelling about their candidacy.
The best interviews are those where you are natural and candid and your true personality, motivation and character emerges. This usually happens when the interview turns into a discussion between two adults and less of a question and answer session.
If you are not great at interviews, i would recommend investing in a few hours of coaching -- so that you can get use to speaking about yourself, your goals and your motivation in the right manner. I alway tell people that the interview is the true make or break point in this entire application process and one where you have to really perform.
Good luck.
