This is a demo model, so I can't really comment on anything besides how insanely thin this device is. It's easy to read the sizing online and not be hugely impressed, but seeing the size in person is another level of "wow."
My three main questions I am very eager to find out:
*Weight—again, numbers are easy, but physically feeling it is different.
*Battery—with reduced size, there's reduced battery life…unless?
*Heat management—being so thin but having the same processor as the S25U—I'm curious how the device feels doing heavy tasks.
Great idea—I'll include an image of that. It seems to be the exact size compared to the ticker side of the S Pen- if not a little thinner
