I think that's kinda what MH01 is getting at, the iPads are appealing to an increasingly shrinking demographic and the Pro versions appear to have only some semblance of popularity in the business sector, yet Apple has no issue pumping money into the iPad lines even if it's nowhere near as profitable as it used to be. So why not bring back the 17 inch MacBooks while they're at it? Even if it only appeals to a minority of users, at least it'll be incredibly useful to that minority and would probably enjoy way more success in the business sector, particularly amongst industry creatives who will get more use out of it than giant tablet with limited functionality for their needs.
This just goes to show that Apple doesn't seem to understand what they're doing lately. Three different iPads whose sole differentiators are really small variations in size, is this really what consumers need or want? This is the sort of nonsense that nearly drove Apple to bankruptcy in the first place.
17" laptops overall are becoming more rare. I have two at my store - both over 1000$. Some people, just assured their eye sight is SOOOOO bad that that extra inch on each side will make it better they'll drop 4-500$ more just to have it.
If you think this only happens in the PC world, I assure you, there are people who buy the 15 MBP when all they need is an air simply because of size.
I'd support a bigger MBP but I'd like them to decouple size and performance.
My ideal matrix would be
Macbook 12" (256 and 512) - the MBr is fine, it's recent and the storage amounts are good. This computer is sold to a specific sort.
Macbook Air 13" (256) (This is the value Mac laptop, with previous-gen processors and slower storage, and a less good screen, but at an affordable price. I honestly think it could be swung for <1000$)
Macbook Pro 13 (i5 256, i5 512 and i7 512) (the 13" is a big sweet spot, so give it more options. Going to an i7 gives more than just a storage difference between them)
Macbook Pro 15 (i5 256 and i7 512) (many people who just buy for the size will do fine with an i5, allowing a lower price)
Macbook Pro 17 (i5 256 and i7 512) (same as the 15")
Other storage options can be CTO.
