I'm looking to buy a 15" Retina MacBook Pro, I'm looking at the website Models and they seem to be pretty inflexible (for instance the 2.3 GHz model you are locked into a 256 GB HD).
So I know this is a little preemptive, but I want to know how the hard drive is configured. For instance, on my current MacBook Pro I swapped out the standard hard drive for a 480 GB SSD. If the new thinner model has a standard SSD I will buy the 2.3 GHz model and add larger hard drive. My worry is it will use a proprietary hard drive like those found in the Air in which case I would be forced to buy the 2.6 GHz model just to get the larger storage I suppose.
Does anyone have any info on this?
