If you’re non-Retina, you’re out.
While not officially announced, it looks like Apple is discontinuing the legacy MacBook Pro from its current lineup of notebooks. The legacy MacBook Pro is the non-Retina model that still includes an optical drive, heavier and undoubtedly less powerful than the current lineup (the most updated model is more than a year old).
This is somewhat plausible with Apple’s plans of replacing its entire notebook line with Retina-based displays. The notebook is still in stock in most stores, but there is a good chance that this will be the last you have seen of the legacy MacBook Pro.
Despite not announcing any new MacBook Pros at WWDC 2016, it is likely that Apple is still scheduled to announce new notebooks by September, to coincide with the release of the new iPhones.
So you are still keen on getting on a MacBook Pro with an optical drive, this may be your last chance.
