Sony's slowly pulling the curtains back on their new laptop. What we've gathered so far is pretty interesting. On the one hand it has a 1600x768 resolution on an 8 inch diagonal display. Apple has a difficult time putting 1600 pixels on a 17 inch diagonal display. We'll wait until we see it, but have a feeling there will be some squinting involved.
Also, it will be running Vista on a 1.33Ghz (probably Atom) processor. Have fun with that
Likely, this thing will not be taking any MacBook Air marketshare.
