Can someone explain to me how/why the 2nd configuration of the 13" wouldn't contain the same specs as the entry 15" rmbp, at close to the same price point? Is it an impossibility due to design?
To me, having a quad-core option with dedicated graphics (and allotting for 16gb ram update) would be the only thing that would justify a 13"option. Otherwise, I feel like most are going to re-assess their workflow and upgrade to the 15" dedicated graphics/quad core, or downgrade to the air.
In fact, they would be stupid not to. At some of the configurations/price points I've seen listed in here, this 13" rmbp would be the most unnecessary computer Apple has ever made. Apple has to know that most professionals who purchase this computer will, likely, also buy external monitors -- could this thing comfortably run a cinema display + pro level software without a dedicated GPU?
On the flip-side, if they provide the aforementioned configuration (2.3GHz quad-core Intel Core i7, 8-16GB 1600MHz memory, 256GB flash storage1,
Intel HD Graphics 4000, NVIDIA GeForce GT 650M with 1GB of GDDR5 memory) at around $1800-2000 it would reach an audience who is currently stuck in limbo -- iMac converts, digital media "do-it-alls", designers looking to future proof themselves, etc
The reason being: even the 15" pros are professional level machines whose screens are, at times, too small for 8+hr/day work periods. Simply put, a smaller (more portable) computer at a price point that allows you to buy 1/2 of a cinema display (getting the iMac experience) before you hit the price of the 15rmbp entry is an easy decision, in my mind, for the aforementioned groups.
Edit: I'd also be curious to see Apple's MacBook Pro sale figures since introducing the 15rmpb...a bang for buck 13rmbp configuration would likely provide Apple with further justification for killing off the old design for good.
