...if the couple iPad/iNavX encounters a great success with yachtsmen, it will probably become a competing product of MacBook/MacENC. !

I wonder. There are as many ways to implement a system as there are yachts and yachtsmen. As I consider a nav system for the boat I am building I am drawn to the idea of having a Mac Mini installed below at the nav station running MacENC, with its added power and versatility, and coupling it to an iPad installed at the helm and, perhaps, in the main stateroom over a wifi network. If the main system went down the iPads would be installed with iNavX to provide serviceable redundancy. I haven't run the numbers, but I suspect the entire system could be put together for a price comparable to, or less than, the cost of the dedicated chartplotter on the boat I sail on now.
