So much for it being a piano, then!
The DGX and CVP also have single finger chords, and they, like the NP-V80 are piano based arrangers.
You see, I prefer to go by what Yamaha calls them, so there is no mix-up...why fuss with the marketing people?
I only have to demo/play them and teach people how to get the most from the instruments.
We can play the definition game till the proverbial cows come home, and the NP-V80 will still be an electronic piano with arranger features, and single finger chords for beginners...AND, the G-70 will still be a Music Workstation (according to Roland, at least) which is actually an arranger that includes a single finger chords feature for beginner workstation players, I suppose.

Personally, I think if all these high end arrangers were intended
only for pros, there would be no single finger chord feature at all.
But, it is quite obviously a carryover from when they were designed primarily for home hobbyist players, much like the organs were many moons ago.
