Ok, thanks for the replies!

What I understand:
-custom colours and materials is not wanted
-typing experience should be flawless
-higher price possible, but comes with huge expectations
-software should be fully integrated

Some remarks:
-custom colours is possible, but has to be decided somewhat early in process, it affects the design. if this is not wanted by you, makes live easier for me. during rev1 had some requests for different colours, hence the question/idea
-the whole camera covering issue will not go away, because the camera is in the middle. it will leave a big hole in your keypad. but i have a trick up my sleeve to eliminate this issue
-the focus is on making it more professional, so no DIY solutions. this is a major focus point
-keypad will be bigger
