it seems pretty obvious that the last MacBook with a built-in DVD and replaceable RAM is not long for this world. But how much longer will Apple sell it and support it? Could it survive another major MBP upgrade like what's rumored to be on the horizon? As it is, a mid2012 MBP bought new will be covered for 3 more years under Apple Care+ and my 2009 MBP has gotten 7 years of OS X upgrades, even though it's technically now an obsolete product. So theoretically if they stop selling the old MBP this fall, it will still be covered under warranty for up to 3 more years, but will the support clock begin in 2012? Or is it sufficiently future-proofed to make it as long as my 2009 MB? And what's the possibility that Apple would continue to sell it, with an internal spec bump like the iPhone SE? Maybe adding a Retina display, and replacing some ports with USB-C and HDMI (rather than continuing to sell the current 13" MBP as an entry level model)? If not that, then what about continuing to sell it with yet another significant price drop? Of course selling it that way would surely limit its longevity and performance? I'd be curious to know what the least supported MacBook model was.
