Ah, yes, that does clear things up a bit.
You may be able to find someone near you who has one of the other e-ink devices. Even if it's not the newest gen of e-ink, it'd give you a good idea of what you're dealing with -- the new one is a lot like the old one, except brighter and more contrasty.
That's how I got my first look at e-ink: contacted someone near me who had one and asked if I could buy him and his iLiad coffee.
