Well I've just got the card, and faxed in the complimentary Priority Pass application (for the Basic cardholder only). I'm not sure how much I use it since I almost always have airline lounge access when I fly, but no harm in having the card.
I was also rather surprised to be given a credit limit larger than my HSBC and Citi cards combined!
The insurance stuff looks good. If you buy your tickets with the card and otherwise have medical insurance that covers you then I don't see any need for any further travel insurance.
