Coté use, you have to like cases with side opening, it is less convenient than those that open downward. Nevertheless, the leather at the hinge is flexible enough to fold completely cover on the back of the device and hold it "normally", a good point for designers.
Side "portfolio," I'm a little disappointed I can not put my license, wallet takes only two cards CB type and has a location on the entire height of the box to put a few tickets bent. I have liked 1 or 2 additional CB typical location because there is room for.
It still gets me out to lunch or for small neighborhood shopping by taking my phone on me, my blue card, my Navigo pass and some money, leaving my big warm overloaded portfolio paperwork.
So overall satisfaction, more by the quality of the product by the practicality.
