Just got my Oberon NC cover this week. It's gorgeous!
I chose the Green Paisley design. Their product is certainly high quality for the price, and their customer service is very good. I also have an Oberon Kindle2 cover which I use with my Sony 950, which is the Red Hummingbird design. I attached photos of both covers if someone wants another example to view.
ProfCrash, good tip on the wool pad. I find it collects cat hair easily.
The straps are placed such that they don't impede any of the side-buttons or the headphones plug. The one thing I was worried about was that the cover wouldn't fold back flatly enough. It is fine, and I am happy. The green paisley cover which is an all-over pattern seems to be more flexible than my red one which has the solid leather at the spine where it bends back.
