AMEX Plum

I am not sure what the new features are with the Plum card but it is interesting and an interesting choice of colors. I imagine that they initially wanted to do Red and some cleaver designer talked them into plum to accompany the elusive ultra-high-end AMEX Black). So there is the green, silver, gold, platinum, plum, and black. I think AMEX provides pretty good service but all of the added concierge and airport lounge stuff that comes with the premium cards seems very intangible.
