Ah, the legendary 14" notebook market! /s
The rMB is an "ultra portable". 14" is not ultra portable by Apple's own current definitions. It would have a larger footprint than the 13" Pro, muddying the current clarity of the product line (ignoring the Airs).
This crystal clear line-up:
12" - Low power, ultra portable
13" - Mid power, very portable
15" - High power, portable
...would become:
12" - Low power, ultra portable
13" - Mid power, very portable
14" - Low power, portable
15" - High power, portable
Nonsensical, and ultimately a pointless product.
Name it pointless but 2 out of 3 people would go for a bigger MB
And how do you define portable?
Is it size or weight? Apple could do a 14" MB with the weight of the 13"MBP but the thinness of the 12" MB.
Believe it or not but there are a lot of people who just don't need the power of a quad core CPU.
and would be more than happy with just a bigger screen by not paying double the price compared to the 15" MBP
20 out of 31 people who visit a Mac enthusiast forum in their spare time would be interested in a new Mac. Funny that.
I don't define it. Apple does, and it's the 12" MacBook.
I would personally love 14" in the form of the 12" with dual 5w cpu, 16gb of ram and 1tb of ssd. I would pay $4000 for this in heartbeat.
