Unfortunately, the weak-lighted, reflective display makes the product in many places almost unusable. Even with anti-reflection film (which is not part of the product and therefore is not included in the rating), this is not entirely resolved. The use in low sunlight and more really makes no more fun. Some reviewers write that they could not understand that. Possibly there is therefore greater differences between the Full-HD and the normal display.
I am not convinced the battery performance. The device must be connected to the grid with WLAN activated after about 1.5 hours iTunes HD video. That may have to do with the fact that you generally have to set the backlight is very high. During the day I did it. Almost always at 90% or at the maximum
The 300 degree Feature I have in practice never be able to make good use of. Some apps go when coming out of full screen, which then can be activated again without hard real keyboard.
