I don't think either the author or other readers her have ever used these laptops in a business / mobile environment.
the comment that a matte screen is a drawback is somewhat myopic IMO, and obviously you don't even use your laptops in well lit bright environments, let alone outdoors. Glossy screens are great for dark environments, but for most people they aren't buying these laptops for DVD colour vibrance (that's why you would buy an LEDlit Glossy laptop), you want it to be functional.
Also, while I appreciate the comment on VGA being a drawback, the connector footprint for DVI is bigger, to me the combo of choice is what I have for mine, VGA+HDMI, you have the best of both worlds and no silly uncommon compromise like mini-DVI other macbooks.
I think like one of the posters above said, it's about an asthetic versus functional laptop. I wouldn't want an Air of work, but I'd want one for travel (either that or a Sony UMPC).
It would've been interesting to add something more Air-ish like the Toshiba R500.
