Let's see, here's what I got:
1) weeks after turning Diamond, I got a mastercard
2) even a week or so later I got 2 luggage tags
3) months after turning Diamond I got a SmartPass
I haven't received any 'normal' EBD card yet, so I'll just rerequest one. I'm not comfortable with just handing out my credit card to a lot of people or having my credit card with me on every trip I make.
When it comes to design, I think it's a big step forward from what we had. We came from a situation which is exemplary from Scandinavian thinking: all cards look the same and have the same boring gray design. There's just a small strip on the bottom indicating you may have a different status (although it's difficult to see the difference between silver and basic. Even basic looked like a gold card that's been in the sun too long). Now at least it's clean that a gold card is gold, a silver card is silver and a basic card is Norwegian blue. And diamond is of course black (anyone ever heard of a black diamond before? I heard of a pink one. They made movies about it. I also heard of blue diamonds, they're singing. Never heard about black diamonds, though...).
