Multi-portion housing of a portable terminal having multiple back covers

A mobile computer having a variable form factor multi-portion housing comprising:

• a first housing portion to provide a first interior for mounting a first electronic component, the first housing portion having a common first mating surface for facilitating coupling to a secondary housing portion;
• the secondary housing portion having a version configuration of a first form factor selectable from a family of different version configurations having a plurality of different form factors contributing to a selectable variable form factor nature of the multi-portion housing, such that each of the version configurations from the family of different version configurations has a same second mating surface that is configured to couple to the common first mating surface;
• wherein the first form factor of the secondary housing portion is configured to facilitate at least one of housing a portion of the first electronic component or housing at least a portion of a second electronic component that is interconnected with the first electronic component.
