... an 16K colour LCD touch screen....

This is an area where I feel pretty ignorant WRT the tradeoffs of different display technologies. My Kenwood HU has a variable-color LCD display that is *much* more readable in daylight than the Empeg VFD, and it looks pretty good at night, but it doesn't look as nice at night as the Empeg, nor would it support Empeg-type visuals -- it has hard-wired LCD sections with particular display areas for track/channel, etc.

My Zaurus has a daylight-viewable LCD display, but it is not very bright. Would your color LCD display "do it all"? Support open-ended visuals and both day and night viewability? Is extra computing power (whether in "the Box" or the display) needed to display color (over current 4-color VFD output)?
