My old 9.7" PocketBook 902 with a glass substrate weighs about 500g. Double it's size to a 13.3" screen and you are looking at a reader that weighs about 1kg (maybe more if the case needs to be even sturdier to keep the device from twisting). There is a good reason why E-Ink does not even produce a 13.3" screen with a front light layer.

boox note pro have light, glass 10.3" screen, and weights 390gr.
They can do it around 600gr max, probably even less. I mean, the ipad pro weights that and have much more on the inside, starting with a 10.000 mah battery vs 4000 on the max 2.
