i found this and thought of the discussions we've had in this thread.

No window for cards - reason being they take up more space with a flap and how often do you need to show someone your ID, in a nation that is against ID cards too with no obligation to carry one.
No coin pockets section - again, makes the wallet really thick
Are you still using yours?
Why do you need lots of extra o-rings? Do they fall off easily or do they perish easily?
Mine's falling apart now, although I've had it a good few years. I want something smarter... maybe one of those brushed aluminium "clip" type wallets.
