Of course unless it can be mass marketed like the ipad, it will cost an arm and a leg.

The thing I wonder about is how well touch screens work when wet... I recall not long ago there was a sharp criticism of a Garmin chart plotter with a touch screen that worked until it rained... at which point the droplets of rain "overrode" the touch aspect.

The touch screens we are using (I work for a wireless communication firm) are "capacitive" in how they sense touch... droplets of water would affect that screen... effectively "shorting" it out.

I like the idea though... seal the whole thing and have some inside base unit for new maps input (via CD or thumbdrive) and where all the sensors and control features come together.

Tacktick has a wireless display, but it really doesn't work to a basestation nor does it have the ability to hook up an autopilot for remote control.
