I watched the video, and it was somewhat interesting, but I had difficulty watching the whole thing.
I hate to say it, but the piano in the video sounded a little like a toy piano to me; the tone was very weak and thin. The sound from the speakers was not very good at all, in my view.
It was interesting, however, that he explained the fact that the keys themselves were part of all the "buttons" that control the settings. That is the same way with my Casio Privia PX310. You have to hold down the function key and then press certain "keys/notes" to make changes. And, that set up is not at all user friendly, at least to me.
My Casio has hundreds of settings and combinations of settings and I've yet to learn how to use all the different settings. I have, however, learned to use the settings that I like and use the most.
I almost always use my Roland KC350 keyboard amp when I play my Casio digital, and am used to the deep, quality sound that the amp produces. The low bass is extraordinary, and all the accompaniment features (drum beats, etc...) sound really good through the amp.
Yes, I'm quite sure digital pianos are getting better and better, and they serve a meaningful purpose; however, I still like my acoustic pianos the best. But I do have a lot of fun with the digital too.
The best of both worlds, I guess you might say...
