I've just received my Neo cover from
http://www.electronicreading.eu and my first impressions of it are very good indeed.
The cover looks like leather, but I'm almost certain it's artificial (it doesn't smell like leather). It's very well padded, and fastens with a magnetic clasp and a press-fastening too, so that's very secure. The inside has a velvet texture, which is comfortable to hold. The bottom half of the left side of the inside of the cover is a full-width "pocket" which could be used for SD cards, business cards, or even (perhaps) your USB cable. There's a cut-out along the top edge of the back of the cover, allowing easy access to the stylus.
The elastic straps which hold the Neo in place are easy to use, but secure, and don't obscure the screen. Along the bottom edge, the strap are positioned to allow direct access to the USB connector, power switch, and headphone socket, and cover the SD socket (which I think is good - it protects it from dirt.
I don't have a camera at hand, but there are pictures of the cover
here.
Finally the price: at €14.99 this cover is an absolute bargain, and half the price of what the official BeBook covers are likely to cost!
Thoroughly recommended! It's wonderful to finally be able to carry my Neo in a proper cover, rather than wrapped up in a tea-towel and bubble-wrap
