More RAM, friends. That's the real story here.
Apple has bumped its Retina MacBook Pro line to include eight gigabytes of RAM as the baseline for the 13-inch models. The 15-inch models sport 16 gigabytes of RAM, standard.
Think of RAM like a tool belt: The bigger the tool belt, the more tools you can have readily available when you need to use them. Or think of RAM like a desk: The bigger the desk, the more papers, pencils, tablets and calculators you can have within arm's reach. This concludes today's lesson on random access memory.
For those of you who are well-heeled, you'll be happy to learn that the top-of-the-line 15-incher has gotten a $100 price drop. Its starting price is now $2,499. If you're poorly-heeled, you'll be happy to know that the non-Retina 13-incher has dropped $100. Its starting price is now $1099.
Processor speeds have been bumped across the Retina line as well, though the non-Retina version "has not been updated with faster internals and remains the same model introduced in June 2012," as MacRumors reports.
