Color guide is excellent, but what about including keyboard-layout switch into it? I am not sure what "stealth" means, as keypad layout..
Random question: would using e-ink display as back-plate of TOHKBD make it bulkier yes, more fragile yes, and-or more expensive also yes? And, most importantly, would the phone recognise it as a second display no? Yes, sounds funny :-)
More relevant question: is the back-light going to be just white yes, or is its colour choose-able, too no? If the latter, then is it possible to choose colour of each LED?
