With the seemingly weak processor, it would make sense for Apple to do away with the peripherals. It will hardly have enough power to give you a satisfactory experience on an external display. In addition, if the focus is truly on portability, then there will hardly be a need to rely on hardware-based external storage either, since there is network-based storage (e.g. Time Capsule), cloud storage (iCloud) or short-range transmission (AirDrop). DVD drives? Died along with the MacBook Air and Retina MacBook Pros. Mouse and keyboards? All Bluetooth-based.
This device is made for people that live in the cloud, have wireless hardware for extra storage and have ideally another computer at home or at work. If you need the extra connectivity, this MacBook just isn’t made for you.
