Thanks Apple. Not only are Mac OS and iOS converging but you are turning your laptops into iDevices, ensuring consumers will buy new laptops when they realize that 4 gigs of RAM and/or a 128 GB SSD are not sufficient to run certain apps.
Surely it should not be so difficult to make SDRAM slots and a SSD slot accessible and your designers should be able to come up with a way that will not mess up the aestetics.
