The 16-inch pen display isn't that heavy but it's not light either.
Anyway, I don't think it's necessary to hold the tablet. You can always buy a stand for the pen display, such as this one shown below.
That's the Parblo PR100 tablet stand I use for for my tablets up to 16-inches and I use that for watercolour work as well as long as the paper can be clipped or placed on the stand without movement.
