I think GPD doesn't remember anymore why the GPD Win was so popular. This looks like a step in the wrong direction.
I don't like it because of the keyboard that is placed behind the screen. That's going to be constantly moving the screen up and down. Or you can just leave it up and wonder why this is moveable at all.
You now also going to need a stand like shown in the pictures and you also want a good case to protect you console and espacially the screen. More costs on console that already is going to be very expensive.
