Screenshot My logic for this mock-up: a) Intel only has 2 processors with the TDP for the Air. b) People want to buy better Air notebooks in a store, without having to resort to BTOs for SSDs or i7s. c) Apple's product line-up has been Consumer/Professional since Jobs' return, so if the "Pro" is "Pro", the "Air" should be the consumer "MacBook", since it starts at such a low price point. d) The lack of more processors could bring Apple to diversify the "Air" platform in 2 configurations: i5/128/4 and i7/256/8. e) Such configurations could be scalable on bigger form factors, still cheaper than the Pro but with more durable batteries. f) Retina display could be added on high-end as an added bonus. g) Apple always liked the Good/Better/Best lineup, this stands true even with Good/Better. The "Air" architecture is scalable for equally powerful Macs even at smaller form factors. h) Higher dimension of the 17" could allow for a discrete graphics card, even if not a top-end one. That is, if Apple introduces 15" and 17" AirBook at the same time (.0001% possibility) i) But 15" ultrabooks were already presented, Apple might want to be the first with 17". j) nVidia could be too late with the new GPUs for Q2 2012, AMD will be ready before Ivy Bridge. Not saying that Apple will do this (reeeeally slim eventuality), but I would like too see what you think, because IMHO this could be one hell of an upgrade to the MBA (MB) lineup! Edit: While you're at it, take a peek at my Pro 2012 mockup. Not wanting to crosspost, but its logic is dependent on the Air mockup you just read.
