I cant say anything definite about response times of the device, since it was 2 weeks ago that i had a quick look at it, but it felt faster. When i get one in my hand, ill do a video review.
As for the glass layer. There is no real alternative so far for the large screens. The touch screen from plastic logic will probably not let you scribble text. What i have seen, its not precise enough for that.
I also do not know, wether the device without the wacom will have a glass based layer or not. I assume though, that it will, since it would probably make more sense from a production point of view.
The DR1000 series is supposedly alot more robust than the iLiad though. Someone mentioned a drop test from roughly 1 meter hight, leaving the device fully functional. Havent seen that yet, and i am probably not willing to try that, once i get mine
