As Apple said, to make the system this small it had to make the logic board tiny. Its even more tightly integrated (and less upgradeable) than the current MacBook Airs. Everything from the RAM to the CPU to the SSD is soldered to the motherboardwhile intrepid MacBook Air owners can at least open up their laptops and swap out the drive, the new MacBook will have the specs you order it with forever. RAM starts and ends at 8GB, and you can get either a 256GB or 512GB SSD.
