The mtvU card is an interesting card. 5% back at bookstores, movie theaters, and restaurants. No one can say for sure whether it's worth it for you. How much do you spend on restaurants each year? Multiply that by 3% (5% back on this vs 2% back using PP Elite). That's how much you gain by having this card. Then you have to weigh that vs the inconvenience of having to carry another card (and possibly another inquiry on your credit report). One other thing to note is that I've heard that all purchases at Amazon.com count as bookstore purchases.

Another option is the Citi Professional card. 3 TY pts/$ for car rentals and restaurants.
