Certainly a screen surface that is perceived to be flush with the rest of the device looks nice, but that aside, is it really a good thing?
Does having a flush surface add another layer over the screen? That would be bad for sharpness and brightness. If it's somehow part of the light-guide or capacity layer, then I guess it's ok.
This image made it look like the actual screen is sunk in, which is bad:
But on the actual device, it doesn't appear so (unless this is a 'simulated' image):
But my biggest worry is that a flush screen is easier to scratch. For example, when you're sliding the device in and out of a bag or pocket, the whole surface gets rubbed on. This is not the case if the screen is sunk in or if the device has a protective case wrap to add a thick lip around the edges. I don't know what kind of glass is on the device, but I hope it's gorilla glass like on the Kindle Fire (if you can believe
wikipedia).
Oh just get a cover you may say. When I got my K3, I also got the amazon leather lighted-cover for it. One day I tried it without the cover and it felt like it was now half the weight and much more enjoyable to hold. I suspect it will be the same with the Voyage + cover.
Lets see:
Kindle 3 (8.5oz) + Kindle lighted leather cover (8oz) = 16.5oz
Kindle Voyage (6.6oz) + Amazon Leather Origami Cover (4.8oz) = 11.4oz
So the Voyage + Cover is 2.9oz heavier than the naked K3 but about 5oz lighter than the K3+cover. Decisions... I wonder why the new cover, which has no built-in light, still costs the same as previous covers that do include a light. I wonder if they will make a cover similar to ipad covers where it only covers the screen and not the back so it can be half the weight.
