I may be interested in helping out with the manual. I write up detailed recreation steps for testing software bugs often at work, and I had a strong language background in the past (writing papers for various classes as well as studying German and French in college and high school). My attention to detail and affinity for precise grammar would be useful, I think. The problem is I've never dealt with the xwhatsit controller or GUI, so my subject matter knowledge is lacking.
Regarding the colors, I think I am set on industrial gray, but do you have a side-by-side comparison of the silver gray and industrial gray? I can't quite picture the difference. Also, do you have any photos of a fully assembled true red or orange keyboard? Seeing the other examples might sway me from industrial gray.
