The Livescribe case you linked to is the one. And the clip you don't like slides right off. I agree and took it off my case.It's because I don't want lint and stuff getting into the air-holes in my pocket.
Awesome about quoting it worked :-). I'm gonna check it out now. Is this what you are talking about?
I don't really like the clip on the back of the livescribe case.

That looks pretty slick...But I just can find the image, not the actual item. LOL
(Sorry for it not being a grasshopper in there, but you get the point :-).
I have to say, the Livescribe case serves its purpose, but I much prefer my leather case from @Ratchett. I know it's more than you're looking for now, but it really works well.
