The sad fact is Apple is silently "testing" their user base right now, and people are allowing themselves to be distracted by Apple's clever ways.
By hyping "retina" people are failing to notice that Apple is switching to a closed non-user upgradeable laptop. While they currently offer both conventional 15" MBP's _and_ Retina models, I assure you they'll justify discontinuing the upgradeable MBP's citing the sales volume & demand for retina.
Slight of hand is Apples specialty. One knows that fact after being an extremely loyal customer of two decades. I really like Apple, but I am disturbed by their direction. Throwaway laptops are not far off no matter how many users are practicing denial.
Apple sells & makes billions on hardware. A fact many seem to lose sight of.
Beginning with an iPhone that had a captive battery, and no battery door, Apple has very cleverly brought us to where we are today. A glued together, super thin, laptop that only they can repair or replace.
I give them a lot of credit, they've made themselves massive amounts of revenue off the backs of their followers. Not many companies can pull that off.
