You don't know what the change in backlight really does to the panel shape. Or whether or not there are other things in that "void" that were not shown in the presentation.
You're saying that a 12" powerbook with LED and no optical would be thinner than MacBook Air?
Please do not use that expression. It does not help you look like you know what you are saying, it does the opposite.
Very easily understood your point. Odd to complain about my expressions with "you did not read or did not comprehend" in yours.
My point is that a keyboard or screen size is a pure constraint on size. Then the footprint, can't be shrunk. You can't go less than 11inches with a full sized keyboard. That is an absolute. But they go closer to 13inches. Why?
You can look at LEDs from rival brands and see less space on either side of the screen. See pic of the Toshiba R500 below (you know the full sized keyboard, 1.75 lb core2duo machine with LED screen and SSD).
By thw way, 0.8 is not thinner than the MBA. The MBA is .76. 0.8 is about where a MBP could be without an optical drive or a MB with a non-plastic case could be. Also see Toshiba R500.
Now I assume something is in that space. But my point is that if you sacrificed some thinness in the tapering, you create more space closer to the track pad. Given no clear constraint on width caused by a screen or a keyboard, ergo it is reasonable to assume that a laptop that was .76 or .8 in thickness across the board without tapering would have space that could be used.
This is not a new or an earth shattering point. Go examine the dimensions of the Toshiba or Panasonic lines and you can see they fit it all in a smaller footprint.
Their issue is that they either opt for a 12 or 14 inch screen. But there is no logical reason when you look inside the Toshiba R500 that Apple could not have shaved 1inch off the width. They are 2inch narrower with a 12inch widescreen. So wouldn't Apple only need 1inch more for a 13inch. . Again that is like what .78 or .8 in thickness.
That Toshiba uses a 2.5inch drive or an SSD, a Core 2 duo processor, motherboard, detachable battery. Its dimensions are 11.1 x 8.5 x .77 (front) and 1 inch (rear). It has a 120GB drive at 5400 rpm (believe it is a 2.5). When they remove an optical drive and use an SSD it is not 1.75lbs.
Do you have any reason to believe if you just changed the screen to 13.3, it would need to add a full 2 inches in width and 1.25lbs in weight?
