Sounds great. Would it be only for landscape.. or portrait as well?
Every BRODIT holder (as other car docks usually) can be turned portrait or landscape. Mine for GTab was mounted onto a tilt swivel so you can also adjust the angle.
They usually build either "passive" and "active" (with cig lighter plug) holders.
You can mount it on a window suction cup system, or on a BRODIT Pro CLip that is the safest car fixation (different clips depending car model and position desired). if you change car you change the proclip and keep your cradle, if you change phone you keep your Proclip and change the cradle.
