Continuing the thought -- laptop systems have the enormous advantage that you don't have to throw the hardware away everytime something is improved. And the hardware itself, being generic and thus produced for a billion purposes, is dirt cheap and good and a commodity.
So I'm thinking -- a laptop in a docking station under the nav table, fixed screen above the nav table, remote RF keyboard and mouse.
That will give electronic charts which are cheap and fully redundant to those in the chart plotters/MFD's.
