I really don't get this article. The iPad can go 4:3 because Apple can guarantee 1 million orders and so their manufacturer is willing to set up a separate line to produce just 4:3 panels. Nobody else can do this because there isn't a million customers who regard widescreen as a critical point of differentiation on a laptop when the same specced 16:9 can be had $10 cheaper.
