A pair of new teardowns from iFixit and Laptopultra have revealed few surprises, and conclude that while the machines are easily openable, they are not easily repairable -- a factor that is likely to be very low-priority among potential buyers, given that the lack of moving parts in the unit also greatly improves reliability. While the new MacBook is completely un-upgradeable internally, the included USB Type C port will offer growing flexibility for any needed external connectivity or expandability.
