Unlike many critical opinions, I found a lot at all. I have SL910 which it is clearly very bad. The SL930 enhances many points it is much more slick and it was truly a SmartPhone hands with the advantage of seeing 2mn appear all our address book with photos and our appointment. I immediately set my Weather applications, directory, etc .. as well as beautiful wallpapers. For that alone it is unique. Everything is relatively well thought even if we still regrets the lack of volume keys and, surprisingly, the audio quality is slightly down compared to the SL910. It is 4 times the price of a non-traditional son, but it's another world.
EDIT: One point that deserves attention (I take a star) is the lack of compatibility between the different Gigaset models. 2 examples: 1: When you call from a SL78H, a S67H or SL910H the SL930A does not display the occupation of the line, it indicates that when the dialing is valid on SL930. 2: For internal calls: The SL78H, S67H well displayed the names of different handsets, the SL910H only displays a keyboard forcing us to know the No. January to June by heart. Gigaset knows (I called) and only solution they propose to go into full SL930.
