We aren't saying that the image is not real, just that there is a black border between the onscreen image and the bezel of the screen in the above picture, it is not a proper representation of the screen size of the 15".
More acurate:
YUP!
That picture is a far more accurate representation. The image in the other one is bordered by black on each side, making the 15" look like a netbook.
Everything else is right on. And I was one of those buyers that was suckered into getting the 15" way back when, then once I finally got my 17" I will never regret getting the bigger book with larger screen and more power.
And truthfully, there isn't any difference in carrying the 17" or using it in a public place. For working pros its a far better option than the 15" IMHO.
