1. A portable computer configurable in a tablet configuration, a laptop configuration, and a closed configuration, said portable computer comprising:a display unit having a display device and a back surface;a base unit having a primary input device and a bottom surface;a latching assembly to maintain said portable computer in one of said closed configuration and said tablet configuration; anda hinging assembly coupling said display unit to said base unit, said hinging assembly having a first hinge with a first axis of rotation and a second hinge with a second axis of rotation, whereinone of said first hinge and said second hinge is rotated to reconfigure said portable computer between said closed configuration and said laptop configuration,said first hinge and said second hinge are rotated to reconfigure said portable computer between said closed configuration and said tablet configuration, andsaid second hinge is oriented to rotate a shaft about a vertical axis, and includes a ball bearing having an inner race coupled to the shaft and an outer race coupled to the base unit, and the shaft is coupled to a support plate. 2. The portable computer according to claim 1, wherein said first axis of rotation and said second axis of rotation are perpendicular. 3. The portable computer according to claim 2, wherein rotation of said first hinge causes said display unit to tilt with respect to said base unit and rotation of said second hinge causes said display unit to swivel with respect to said base unit. 4. The portable computer according to claim 3, wherein said display unit has a first orientation when said portable computer is in said laptop configuration, and further wherein said second hinge operates in a range of rotation having an upper limit, such that said display unit has a second orientation opposite to said first orientation when said second hinge is rotated to said upper limit of said range of rotation of said second hinge. 5. The portable computer according to claim 2, wherein said first hinge has a range of rotation with an upper limit of 90 degrees. 6. The portable computer according to claim 2, further including a cable for transmitting electronic signals, said cable having a first end coupled to said base unit and a second end coupled to said display unit, wherein a portion of said cable passes through said shaft. 7. The portable computer according to claim 2, further including a locking pin selectively insertable into a first cavity to prevent said second hinge from rotating. 8. The portable computer according to claim 7, wherein said locking pin is inserted into said first cavity when said portable computer is in said laptop configuration. 9. The portable computer according to claim 7, further including a second cavity when said portable computer is in said tablet configuration. 10. The portable computer according to claim 7, wherein said locking pin is inserted into said first cavity by movement of a mechanical actuator. 11. The portable computer according to claim 10, wherein said mechanical actuator is one of a lever arm and a push button. 12. The portable computer according to claim 2, said latching assembly further including a latching arm having a first projection and a latch body having a first cavity adapted to receive said first projection to maintain said portable computer in one of said closed configuration and said tablet configuration. 13. The portable computer according to claim 12, said latching arm further including a second projection, wherein said first cavity is also adapted to receive said second projection, and further wherein said first projection is received by said first cavity to maintain said portable computer in said closed configuration, and further wherein said second projection is received by said first cavity to maintain said portable computer in said tablet configuration. 14. The portable computer according to claim 12, said latching arm further including a second projection and said latch body further including a second cavity adapted to receive said second projection wherein said first projection is received by said first cavity to maintain said portable computer in said closed configuration, and further wherein said second projection is received by said second cavity to maintain said portable computer in said tablet configuration. 15. A method for reconfiguring a portable computer among a tablet configuration, a laptop configuration, and a closed configuration, wherein said display device is contained in a display unit and said primary input device is contained in a base unit, said method comprising:when said portable computer is in said closed configuration such that said display device and said primary input device are contained between a back surface of said display unit and a bottom surface of said base unit, rotating a first hinge to tilt said display unit relative to said base unit until said portable computer is in said laptop configuration;rotating a second hinge when said portable computer is in said laptop configuration to swivel said display unit relative to said base unit;rotating said first hinge after said second hinge has been rotated to place said portable computer in said tablet configuration; andclosing a latching assembly by inserting a latching arm into a latching block, when said portable computer is in said tablet configuration to couple said base unit to said display unit, wherein said latching arm is mounted on a first portion coupled to said display unit and said latching block is mounted on a second portion coupled to said base unit. 16. The method according to claim 15, wherein rotating said second hinge includes removing a locking pin from a cavity when said portable computer is in said laptop configuration. 17. The method according to claim 15, wherein rotating said second hinge includes inserting a locking pin into a cavity after said display unit has been swiveled relative to said base unit.
