I recently purchased the Boxwave horizontal case. I like it a lot. Yes, the plastic along the bottom edge covers the keyboard, and is hidden when the N810's screen slides down. I actually think it gives the keyboard a better feel for some reason. Use of leather conditioner from time to time may help keep the leather feeling supple new, especially if you live in a dry climate.

Only downside is I don't see how this could fit in my pocket. It easily doubled the thickness of the package, but at least I have peace of mind that it's safe from harm's way.
