1. A portable electronic device, comprising: a housing formed from electrically conductive material;a moisture flow inhibiting seal comprising an electrically conductive pathway in contact with the electrically conductive material of the housing; andan external feature configured to receive a user input, the external feature being connected to an internal switch displaced from the external feature by way of an electrically conductive arm that fits through the moisture flow inhibiting seal,wherein a grounding pathway is formed between the electrically conductive arm, the electrically conductive pathway of the moisture flow inhibiting seal and the electrically conductive material of the housing, the grounding pathway allowing a quantity of charge deposited at the external feature to flow directly to the electrically conductive material of the housing, thereby bypassing the internal switch. 2. The portable electronic device as recited in claim 1, wherein the housing provides a chassis ground and has a cavity sized to enclose a plurality of operational components at least some of which are susceptible to damage when exposed to an electrostatic discharge (ESD) event. 3. The portable electronic device as recited in claim 1, wherein the electrically conductive pathway of the moisture flow inhibiting seal is formed by adding a conductive dopant to at least a portion of the moisture flow inhibiting seal. 4. The portable electronic device as recited in claim 1, wherein the housing comprises an internal anodized surface, at least a portion of which is substantially removed to allow contact between the electrically conductive material of the housing and the moisture flow inhibiting seal. 5. The portable electronic device as recited in claim 1, wherein the external feature comprises a slide switch. 6. The portable electronic device as recited in claim 1, wherein the electrically conductive pathway of the moisture flow inhibiting seal comprises a plurality of conductive particles embedded within the moisture flow inhibiting seal. 7. The portable electronic device as recited in claim 1, wherein the electrically conductive material is aluminum. 8. The portable electronic device as recited in claim 1, wherein the electrically conductive material of the housing is substantially covered by an oxide layer and wherein the oxide layer over a surface portion of the housing in contact with the moisture flow inhibiting seal is removed. 9. The portable electronic device as recited in claim 8, wherein the oxide layer is removed by a laser etching process. 10. The portable electronic device as recited in claim 8, wherein the oxide layer is an anodized layer comprising aluminum oxide. 11. A media player, comprising: a housing having an electrically conductive surface disposed on an inside surface of the housing; anda user interface, comprising: an external feature extending through an opening in the housing and arranged to receive a user input event, andan electrically conductive member arranged to couple the external feature to an internal switch by way of a metal base portion; anda metal label conductively mounted to the metal base portion by a conductive adhesive such that a conductive pathway is formed between the external feature and a portion of the electrically conductive surface of the housing by way of the metal label and the metal base portion, the conductive pathway allowing a quantity of charge deposited at the external feature to flow directly to the electrically conductive surface of the housing, thereby bypassing the internal switch. 12. The media player as recited in claim 11, wherein the user interface comprises a switch assembly. 13. The media player as recited in claim 12, wherein the metal label is configured to display a color indicative of an operating mode of the media player when the media player is in at least one of a plurality of modes. 14. The media player as recited in claim 11, wherein the electrically conductive surface is aluminum. 15. The media player as recited in claim 11, wherein the conductive adhesive is solder. 16. A method, comprising: mounting a moisture resistant seal to an electrically conductive inside surface of a housing, the moisture resistant seal comprising an electrically conductive pathway and a slit, wherein the electrically conductive pathway is in contact with both the slit and a conductive surface of the housing; andinstalling a user interface assembly within the housing such that the user interface assembly is disposed through an opening in the housing and through the slit in the moisture resistant seal, wherein a first end of the user interface assembly comprises an external feature configured to receive a user input event and a second end of the user interface assembly comprises an electrically conductive arm coupled with an internal switch within the housing,wherein a grounding path is formed between the external feature and the conductive surface of the housing by way of the electrically conductive arm and the electrically conductive pathway of the moisture resistant seal, the electrically conductive pathway allowing a quantity of charge deposited at the external feature to flow directly to the conductive surface of the housing, thereby bypassing the internal switch. 17. The method as recited in claim 16, further comprising: laser etching a portion of an oxide layer covering the electrically conductive inside surface. 18. The method as recited in claim 16, wherein the housing comprises aluminum substantially encased in an oxide layer. 19. The method as recited in claim 16, wherein the moisture resistant seal further comprises rubber infused with metallic particles, the metallic particles forming the electrically conductive pathway. 20. The method as recited in claim 16, wherein the user interface assembly is a button assembly and the external feature is a slide switch.
