I thought we were talking about footprint, which is length x width, not diagonal screen size. Since the MBA is the same length as similar ultraportables, width would be the missing dimension, so that's what I talked about.Also, there is no need to play trick and change subject, MBA is 13.3" screen, not 13.3" wide, and we are not talking about width here, everybody knows it.
That's you. I believe thickness and weight are the top two factors. You're the one talking about "footprint" by which you clearly mean "width".exactly why do you believe "extremely small" fraction of ultraportable users care more about footprint than weight?
"Discussion need to be" coherent and in English.You just made that bold statement with no data support? extremely small fraction? please, discussion need to be honest.
It's simple, really. Thickness and weight are the factors discussed in the text of reviews of ultraportables (i.e. notebooks under 4 pounds according to Sony, Dell, and CNet). Many reviews don't even list footprint dimensions. Further, a 12" ultraportable doesn't compete with another based on its width--I've never heard anyone say "I'm buying the Fujitsu instead of the Sony because it is 0.4" narrower"--once people decide to buy an ultraportable (11-13" screens) or a UMPC (~10" and under), there's absolutely no empirical reason to believe that width is more important than either thickness or weight.
Lots of people choose the Sony because it's thinner or the Fujitsu because it's lighter. Quibbling over a half inch of width wouldn't come into play unless thickness and weight were inconclusive.
