My Nook case arrived from B&N today. It's a nice fit and it's the clamshell type of case, which is what I like. It makes the Nook seem smaller, strangely enough.
It has a nice little elastic band on the back that can be used to hold the cover closed, giving it a bit more protection. All in all I'm pretty pleased with this thing.
I got it while it was on sale for $15 which makes it even better.
