Is it acceptable for candidates to have a cheat sheet during an interview?

This one will have to be quick as I am quite busy today. But I was searching LinkedIn for candidates to send to a company and I came across a thread: "Is it acceptable now for candidates to refer to notes during an interview to answer a question?" This is interesting. I have mixed feelings on this. On one hand I get it for a seasoned candidate who has an extensive career at a few different companies; however, if I was interviewing a candidate and they had notes they would refer to before answering some of my questions I'm not sure how I would take that. So far there are only two comments on the thread - both say yes it is acceptable (in so many words). What do you think?
