CMC 2

 The modern CMC has both holographic projector capabilities and holographic input capabilities. The device can be set up to project a motion monitoring keyboard to allow extended input. It can also project 2D screens as well as more conventional 3D holographic objects.

Such functionality, when mated with the network connectivity of the CMC allows the device to act as a computer workstation, all that is required is a flat surface on which to stage the CMC. While the input keyboard can be projected without requiring a surface, it is almost impossible for a human to "air type" consistently. Of course the device is quite capable of responding to voice commands, as well as the more conventional touch display.
Like most modern TLA portable devices the CMC can be recharged using its included wireless charger. The typical ruggedized CMC also includes the ability to recharge by being left in the sun, thanks to its solar power receptor screen.
