A small form-factor keyboard or keypad for key structures is provided in which individual key structures have a contact surface on which there is a center reference and a peak. The center reference and the peak or offset, so that an offset distance between the center reference and the peak is greater than or equal to zero. The offset distance for at least two or more key structures in the plurality of key structures may different. The difference in the offset distance may be based on a position of the individual key structures relative to a first reference line.

What is claimed is: 1. A keypad comprising: a plurality of key structures comprising two or more adjacent pairs of key structures that extend from an underlying surface, wherein the two or more adjacent pairs of key structures are distributed primarily in a first direction; wherein each key structure in the plurality of key structures includes an exterior surface for receiving user-contact, the exterior surface of each key structure having a center reference and a peak; and wherein for each of the two or more adjacent pairs of key structures, (i) a peak-to-peak distance between the peak of each key structure in the pair is greater than a distance between the center reference of each key structures in the pair, (ii) a height that the peak of each key structure in the pair is extended from the underlying surface is approximately equal; and (iii) a height that the center reference of each key structure in the pair is extended from the underlying surface is approximately equal. 2. The keypad of claim 1, wherein the peak-to-peak distance between the peaks of each of the adjacent pairs of key structures is about the same. 3. The keypad of claim 2, wherein the distance between the center reference of each of the adjacent pairs of key structures is about the same. 4. The keypad of claim 1, wherein the underlying surface forms a medium that interconnects each of the plurality of key structures, and wherein each key structure in the plurality of key structures has a height that is based on a dimension that extends vertically outward from the medium. 5. The keypad of claim 1, wherein the plurality of key structures form a QWERTY style keyboard. 6. The keypad of claim 1, wherein a footprint of individual key structures in the plurality of key structures is asymmetrical. 7. The mobile computing device of claim 1, wherein the plurality of key structures form a QWERTY style keyboard. 8. The mobile computing device of claim 1, wherein a footprint of individual key structures in the plurality of key structures is asymmetrical. 9. A mobile computing device comprising: a housing; a keypad provided on a surface of the housing, wherein the keypad includes a plurality of key structures comprising two or more adjacent pairs of key structures that extend from an underlying surface, wherein the two or more adjacent pairs of key structures are distributed primarily in a first direction; wherein each key structure in the plurality of key structures includes an exterior surface for receiving user-contact, the exterior surface of each key structure having a center reference and a peak; wherein for each of the two or more adjacent pairs of key structures, (i) a peak-to-peak distance between the peak of each key structure in the pair is greater than a distance between the center reference of each key structures in the pair, (ii) a height that the peak of each key structure in the pair is extended from the underlying surface is approximately equal; and (iii) a height that the center reference of each key structure in the pair is extended from the underlying surface is approximately equal. 10. The mobile computing device of claim 9, wherein the peak-to-peak distance between the peaks of each of the adjacent pairs of key structures is about the same. 11. The mobile computing device of claim 10, wherein the distance between the center reference of each of the adjacent pairs of key structures is about the same. 12. The mobile computing device of claim 9, wherein the underlying surface forms a medium that interconnects each of the plurality of key structures, and wherein each key structure in the plurality of key structures has a height that is based on a dimension that extends vertically outward from the medium.
