Any universal cradle/holder will work but you get what you pay for. The Brodit mounts are reported to be excellent quality and allow the Kaiser to be used closed or with the keyboard out. They are available as passive or active (built in charger) and both types alow you to rotate between Landscape and Portrait. They work well with the Proclip mounts which are specific for individual cars. I wouldnt trust a suction type mount with my Kaiser , that may just be down to my driving style though. Have a look at the other threads on here for more inspiration. As far as I am aware no one currently sells the Holy Grail of mounts which would be Charging/Audio out/Mic/Rotation/Keyboard open or closed. There are however several homebrew solutions in the other threads on here and in the Hermes forums.
