however, the question as to why in the ipad and not in the MBA, i think, still stands.
For me it's pretty obvious.
People rarely use their computers at places where there isn't a wifi connection already available.
You never use your MBA walking around, sitting in a car or on a bus but you do use your iPad while doing those things.
But the carrier term for iPads is month to month. I figure it would be the same for a MBA.
I think most of you guys are right though. It's not in the cards. At least not for next year.
I was also thinking about screen size, since it is rumored that Apple may be considering a 15" Air. Based off the current 13" case, if they did away with the bezel, they could actually fit a 15" screen in there (12.8" x 8.94" = roughly 15.6"). At a minimum they wouldn't have to increase the size of the MBA by much - which would be awesome.
