I just wanted to say that demoing the macbook air's sound capabilities was ruined for me because the speaker is placed under the keyboard on the far right side of the notebook. Its placement is really stupid as when I'm listening to music it just sounds unbalanced and I watching movies I would be disappointed. I don't care about mono speakers, but at least like on thinkpads they have the speaker in the center. I think that people should realize this before buying. I do see the lines that people are talking about but they do not bother me NEARLY to the degree that the Sony Vaio Z does. It's like a combination of flicker + waves of diagonal lines on the Vaio Z. I was ready to roll on the air until I realize that the speaker placement is really dumb.
