I'm thinking of this case. I don't know how much I'd use the keyboard, but I like that the back matches the back on the N7 and it's a hard case. (There are two cheaper variants listed in this thread.)

I'm in the same boat. I had the Poetic hard back. It was nice but not very stylish. I'm currently using a Timbuk2 padded envelope for travelling and just enjoying the naked N7.
