I know.
What I meant was, that when I removed the glass from my Kobo Aura (a long time ago) I cut through the tag and realized I was f*cked. However, I didn't stumble on (the remains of ) a tag this time, yet.
Apart from the glue layer, on top of the Wacom layer, (that had to be warmed by a heat gun before I could remove the glas shards,) there was no connection other than an extra glue strip over the black inserts in the iron.
That's why I did the experiments.
Another reason is that the screen was _very_ heavily cracked and the touch functionality remained. I don't expect that if it was a conducting layer created by vapour deposition. However, the conducting layer was against the glue layer, so maybe it didn't crack.
One thing I do really like, apart of the disappearance of all cracks, is the weight: The Note Pro without a glass layer is really light! So I will have to make sure to get a light plastic digitizer. I don't want that weight back in my hands.
