No, but my company, Quince Studio, is working on a mountable case for the car as well. I will update this forum when it is ready. We currently have designer walnut and distressed leather cases.
Yes, I've bought one, but I'm not impressed. Had to wait ages for it to arrive. Wall mount plastic part looks cheap and is a creamy white which doesn't look great. Also I doubt the case will fit an iPad when its out; I wonder if they will do a new version. My main issue with it is that there's no provision for charging. The Adith U-bar looks good but doesn't seem to be shipping yet.
