I can say that because the #1 priority of an ultra compact is connectivity <-- That is the intention of an ultra compact, to be able to take it to more places than a conventional laptop and still have full connectivity. So why in the world would the MBA not have built-in 3G reception? And the USB port is so geared towards "looks" that it can't even accommodate an external 3G anttena. Is Apple Inc so delusional as to think wi-fi is everywhere? Certainly not within the lifetime of this Rev A MBA. Hence, given the lack luster features of the MBA, we can conclude that it purpose is to serve as a fashion item more than anything else.
