Unfortunately you have to - at least on the front I have this understanding - to put up with smaller films which no longer look buckle and slide size conditionally as unobtrusive as it is the case with planar devices. Also on the back is the film for me an optical "interference factor" is, who was with the predecessor is not so noticeable. At the end there is a - necessary for me - a compromise between new design and protection of the display and the back.
As nice as the curves of the device are also catchy, the iPhone 6 with a Case. In this respect, you can probably do without the film to the back and here take the right voices aussehnde Apple Leather Case. For the front I'm hoping for a real glass protection which is made with the manufacturer vault and then looks perhaps more pleasing than the "too small" film.
Conclusion: As the first set of films recommended optically unfortunately somewhat disturbing than before and not provide full protection of the entire display surface.
