the reason we buy this stuff is only 'yes, it's now available and its a good size." when before no one could have ever thought a 12-inch Air would ever make sense...... Lets hope this doesn't come out.... We need a choice, not a middle man.
I'm sorry, I don't follow. Yes, 12" is between 11" and 13", but I really don't think this is the long term plan. the 11" and the 13" will most likely be dying off.
Most likely the roadmap is 12" Air up to 13" Pro up to 15" Pro and actually reduce the SKU count. Heck, that is only 3 laptops! with the current Air continuing alongside the new 12" model and the soon to be discontinued non-retina 13" Pro, that is 6 models, which is probably 2 too many.
Alternatively, this new 12" laptop could be released under the old simple "MacBook" moniker, and then you would have 2 sizes of MacBook Air, the MacBook, and 2 sizes of MacBook Pro. Only 3 models, 2 of them that come in 2 different screen sizes.
Another thought that came to me would be to convert the current MBA line to the simple "Macbook" moniker instead, and making them the entry level laptops. This new 12" model that is meant to bring portable to a new level takes on the Air moniker.
Just some random thoughts on how this could all develop. Keeping the current MBA unchanged as the entry level MacBook makes a whole lot of sense if they don't go retina. The new 12" model would have to beat it in every category though for this to happen - portability, performance, premium.
