Does anyone have an American Express Platinum card?

As far as I can tell, the only reason someone would want to spend the extra 300 dollars a year on a platinum card for AMEX, is if they travel a lot. I have a Gold AMEX, and I love it. American Express really makes things easier for me. But I don’t see the reason to go to a platinum. Does anyone have one? Do you like it? Why didn’t you get the gold card?
