Apple finally got the non-upgradeable memory messaging right for the MacBook Pro Retina (I’m not sure of the exact date at which the final update was made).
There were at least three versions of the memory description over the past few weeks, so it’s clear that someone at Apple didn’t think through the “serve the customer” mission that underlies all proper marketing.
I’m pleased to see that Apple has fessed up and made the point clear, though not every buyer will understand the implications fully, or even know in advance whether 8GB is enough (for 3 years?!), so I’d prefer to see the 8GB option eliminated on such an expensive top-end laptop. Apple’s enormous pricing clout makes that option relatively modest in cost.
