The portable media device of claim 1, wherein the touchpad comprises a plurality of spatially distinct zones, each of the zones having a corresponding indicator for generating a distinct user input signal when the touchpad is depressed in the region of the input zone. 5. The portable media device of claim 4, wherein the touchpad comprises at least four spatially distinct zones. 6. The portable media device of claim 1, wherein the touchpad is based on a polar coordinate system. 7. The portable media device of claim 1, wherein the touchpad is circular. 8. The portable media device of claim 1, wherein the selection comprises a selection for a media file. 9. The portable media device of claim 1, wherein the housing defines a space and wherein the touchpad and the housing are configured to enable the touchpad to float within the space of the housing. 10. The portable media device of claim 1, wherein the touchpad is configured to enable one or more clicking actions. 11. A portable media device, comprising: a housing, and an input device associated with the housing, the input device configured to gimbal to enable the input device to float relative to the housing while being constrained thereto and to enable the touchpad to move perpendicular relative to a surface of the housing when an input surface of the touchpad is parallel to the surface of the housing, thereby enabling the input device to move in multiple degrees of freedom relative to the housing and to receive a rotational input from a user, wherein the input device comprises a plurality of spatially distinct zones, each of the zones having a corresponding indicator for generating a distinct user input signal when the input device is depressed in the region of the zone, wherein each of the multiple degrees of freedom is associated with a function of the device and wherein the gimbal action of the input device enables a user of the portable media device to make a selection. 12. The portable media device of claim 11, wherein the portable media device comprises a media player. 13. The portable media device of claim 11, wherein the input device comprises a touchpad. 14. The portable media device of claim 11, wherein the input device comprises at least four spatially distinct zones. 15. The portable media device of claim 11, wherein the input device is based on a polar coordinate system. 16. The portable media device of claim 11, wherein the input device is circular. 17. The portable media device of claim 11, wherein an input surface of the input device is substantially co-planer with an external surface of the housing. 18. The portable media device of claim 11, wherein the housing defines a space and wherein the input device and the housing are configured to enable the input device to float within the space of the housing. 19. The portable media device of claim 11, wherein the input device is configured to enable one or more clicking actions. 20. A portable media device, comprising: a housing, and an input device comprising a touchpad within the housing, the input device configured to gimbal to enable the input device to float relative to the housing while being constrained thereto and to enable the touchpad to move perpendicular relative to a surface of the housing when an input surface of the touchpad is parallel to the surface of the housing, thereby enabling the input device to move in multiple degrees of freedom relative to the housing and to receive a rotational input from a user, wherein the touchpad comprises at least a plurality of spatially distinct zones, each of the input zones having a corresponding indicator for generating a distinct user input signal when the input device is depressed in the region of the input zone, wherein each of the multiple degrees of freedom is associated with a function of the device and wherein the gimbal action of the input device enables a user of the portable media device to make a selection. 21. The portable media device of claim 20, wherein the touchpad comprises at least four spatially distinct zones. 22.
