1. A portable computer comprising: a base;a lid;a base cylinder extending from the base, a length of the base cylinder being greater than a diameter of the base cylinder, the base cylinder including a base rod and a base shell encasing the base rod, the base shell having a lower hardness than the base rod;a lid cylinder extending from the lid, a length of the lid cylinder being greater than a diameter of the lid cylinder, the lid cylinder including a lid rod and a lid shell encasing the lid rod, the lid shell having a lower hardness than the lid rod; anda link coupling the base cylinder to the lid cylinder, a length of the link in a direction parallel to a direction in which the base cylinder and the lid cylinder extend through the link being greater than a width of the link in a direction perpendicular to the direction in which the base cylinder and the lid cylinder extend through the link, the link being in direct contact with both the base cylinder and the lid cylinder and fixing a positional relationship between the base cylinder and the lid cylinder so that the base shell frictionally engages with the lid shell. 2. The portable computer of claim 1, wherein the base rod comprises steel. 3. The portable computer of claim 1, wherein the base shell comprises rubber. 4. The portable computer of claim 1, wherein the base shell is attached to the base rod by an adhesive. 5. The portable computer of claim 1, wherein the base shell is mated to the base rod by splines. 6. The portable computer of claim 1, wherein the base shell has a thickness of less than one millimeter. 7. The portable computer of claim 1, wherein the base shell has a Shore D durometer between fifty and sixty. 8. The portable computer of claim 1, wherein the base shell has a Shore D durometer between thirty and eighty. 9. The portable computer of claim 1, wherein the link fixes the positional relationship between the base cylinder and the lid cylinder so that the base cylinder and lid cylinder are generally parallel to each other. 10. The portable computer of claim 1, wherein a distance between central axes of the base cylinder and the lid cylinder is less than an uncompressed diameter of the base cylinder. 11. The portable computer of claim 1, wherein the link enables the lid to rotate about the base from a first position in which a front of the lid is facing a top of the base to a second position in which a back of the lid is facing a bottom of the base. 12. The portable computer of claim 1, wherein the base cylinder is exposed beyond the link and the lid cylinder is exposed beyond the link. 13. The portable computer of claim 1, wherein the link includes two pieces, the two pieces of the link being attached by fasteners. 14. The portable computer of claim 1, wherein the link forces the base cylinder and the lid cylinder into close, compressed contact with each other. 15. A method of assembling a portable computer, the method comprising: securing a base cylinder to a base of the portable computer, the base cylinder being without teeth, a length of a portion of the base cylinder that frictionally engages a lid cylinder being greater than a diameter of the portion of the base cylinder that frictionally engages the lid cylinder;securing the lid cylinder to a lid of the portable computer, the lid cylinder being without teeth, a length of a portion of the lid cylinder that frictionally engages the base cylinder being greater than a diameter of the portion of the lid cylinder that frictionally engages the base cylinder;securing the base cylinder to a link so that the base cylinder is in contact with the link; andsecuring the lid cylinder to the link so that the lid cylinder is in contact with the link, the securing of the base cylinder to the link and the lid cylinder to the link fixing a positional relationship between the base cylinder and the lid cylinder so that the base cylinder frictionally engages with the lid cylinder, a length of the link in a direction parallel to a direction in which the base cylinder and the lid cylinder extend through the link being greater than a width of the link in a direction perpendicular to the direction in which the base cylinder and the lid cylinder extend through the link. 16. The method of claim 15, wherein the securing the lid cylinder to the link comprises: placing the base cylinder onto a first part of the link;placing a second part of the link over the base cylinder and the first part of the link to enclose the base cylinder between the first part of the link and the second part of the link; andsecuring the second part of the link to the first part of the link by fasteners. 17. The method of claim 15, wherein the securing the lid cylinder to the link comprises fixing the positional relationship between the base cylinder and the lid cylinder so that the base cylinder and lid cylinder are generally parallel to each other. 18. The method of claim 15, further comprising: forming the base cylinder by encasing a rod with a shell, the shell having a lower hardness than the rod,wherein the rod of the base cylinder extends from the base of the portable computer, and the shell of the base cylinder frictionally engages the lid cylinder. 19. A portable computer comprising: a base comprising at least one processor, at least one memory, a keyboard, and a tactile input device;a lid comprising a display coupled to the at least one processor;a base cylinder extending from the base, the base cylinder including a base rod extending from the base and a rubber base shell encasing the base rod, a length of the rubber base shell being greater than a diameter of the rubber base shell;a lid cylinder extending from the lid, the lid cylinder including a lid rod extending from the lid cylinder and a rubber lid shell encasing the lid rod, a length of the rubber lid shell being greater than a diameter of the rubber lid shell; anda link coupling the base cylinder to the lid cylinder, the link being in direct contact with both the base cylinder and the lid cylinder and fixing a positional relationship between the base cylinder and the lid cylinder so that the base cylinder and lid cylinder are generally parallel to each other and the rubber base shell frictionally engages with the rubber lid shell, a length of the link in a direction parallel to a direction in which the base cylinder and the lid cylinder extend through the link being greater than a width of the link in a direction perpendicular to the direction in which the base cylinder and the lid cylinder extend through the link. 20. The portable computer of claim 19, wherein the rubber base shell has a thickness of less than one millimeter and a shore D durometer between fifty and sixty. 21. The portable computer of claim 19, wherein the base rod is made of steel. 22. A portable computer comprising: a base;a lid;a base cylinder extending from the base, a length of the base cylinder being greater than a diameter of the base cylinder, the base cylinder including a base rod and a base shell encasing the base rod, the base shell having a lower hardness than the base rod, a length of the base shell being greater than a diameter of the base shell;a lid cylinder extending from the lid, a length of the lid cylinder being greater than a diameter of the lid cylinder, the lid cylinder including a lid rod and a lid shell encasing the lid rod, the lid shell having a lower hardness than the lid rod, a length of the lid shell being greater than a diameter of the lid shell; anda link coupling the base cylinder to the lid cylinder with a portion of the base cylinder being exposed, a length of the link in a direction parallel to a direction in which the base cylinder and the lid cylinder extend through the link being greater than a width of the link in a direction perpendicular to the direction in which the base cylinder and the lid cylinder extend through the link, the link fixing a positional relationship between the base cylinder and the lid cylinder so that the base shell frictionally engages with the lid shell.
