What makes Apple think it's only the Asian market that would like a 14" MacBook Air. I imagine a 14" might offer the feel of a larger 15", which preserving much of the compactness of the 13" -- particularly if Apple can do what HP did, and extend the screen more to the edges of the lid, rather than having a large edge margin.
I prefer the form factor of 14" laptops, as well.
Would this be only sold in Asain markets?
Either way it makes no sense to have 11", 13", 14", 15", and 17" options.
I said a while ago that I thought Apple might go with new sizes for the new MB range:
12" & 14" MBA
16" & 18" MBP
If they eliminate the border around the screen and go with an edge to edge screen instead they should be able to increase the screen size without increasing the overall footprint of the machines.
The addition of a new 14" form factor seems out of place unless Apple is going to consolidate the notebook line into a single line of "MacBooks" and changes the lineup to distinguish more precisely between models with integrated graphics (current MBAs) and models with discrete graphics (MBPs). A 14" form factor would provide enough space for a low-end, discrete graphics chip and retain portability with the 13", while also avoiding confusion with the 13" model which would provide less graphics processing power. Thus I could envision the following line-up:
11" & 13" MBA (integrated graphics)
14", 15", & 17" (dedicated graphics)
I am, however, very dubious about this story.
