What is claimed is: 1. A pen-based computing system comprising: a tablet unit including a display screen and an electronic assembly housed within an enclosure; and a separate base unit including two panels connected via a hinge, a first one of the panels bearing a keyboard, and a second one of the panels being arcuately displaceable relative to the first panel to prop the tablet unit in a viewing position in which the display screen makes a viewing angle with the keyboard of greater than 90 degrees, wherein the tablet unit and the first panel have complementary formations to prevent sliding movement of the tablet unit relative to the first panel when in the viewing position, wherein the complementary formation of the tablet unit comprises at least one wheel rotatably mounted to the enclosure of the tablet unit, and wherein the complementary formation of the first panel comprises a complementary track. 2. The system of claim 1, wherein each wheel includes a plurality of teeth. 3. The system of claim 1, wherein the tablet unit further comprises a braking mechanism to check the free rotation of the at least one wheel. 4. The system of claim 3, wherein the braking mechanism comprises a braking element in frictional contact with the at least one wheel. 5. The system of claim 4, wherein the braking element includes a spring biased to bear against the at least one wheel. 6. The system of claim 1, wherein the wheel have a plurality of teeth to engage complementary teeth in the track of the first panel. 7. The system of claim 1, further comprising: a flexible hinge connecting the first and second panels; wherein the second panel comprises a curved portion near the hinge; and wherein, when the tablet is in a viewing position and the second panel is in contact with the tablet unit and the bottom of the first panel rests on a planar surface, the curved portion of the second panel lies in the same planar surface as the bottom of the first panel. 8. A pen-based computing system comprising: a base unit including a first and second panel connected by a flexible hinge; wherein the first panel has a generally flat body including a keyboard, and wherein the flexible hinge comprises a curved section extending into the second panel; a tablet unit comprising: a processing component including a processor coupled to a memory; a display component including a digitizer to capture data entered with the pen and a display screen coupled to the processing component; an enclosure defining a housing for the processing component and the display component, wherein the enclosure includes a mechanical stop to check sliding motion of the tablet unit relative to the first panel when the tablet unit is supported on the first panel so that it makes an acute angle therewith; wherein the second panel is in contact with the tablet unit in the said acute angle with the first panel; wherein the curved section of the hinge is coplanar with the bottom surface of the first panel; wherein a load from the tablet unit is directed through the second panel to the hinge, wherein the bend in the curved section of the hinge disperses some of the load acting on the hinge away from the first panel, and wherein the mechanical stop comprises a rotatable member, rotatably mounted to the enclosure and shaped and dimensioned to rotate within a complementary track in the base unit. 9. The tablet unit of claim 8, wherein the rotatable member comprises a wheel having a plurality of teeth to engage complementary teeth in the track of the base unit. 10. The tablet unit of claim 8, further comprises a braking mechanism to check free rotation of the rotatable member. 11. The tablet unit of claim 10, wherein the braking mechanism comprises a biasing element, which bears against the rotatable member to check free rotation thereof. 12. The system of claim 8, wherein the second panel is displaceable relative to the first panel to prop the tablet unit in a viewing position in which the display screen makes a viewing angle with the keyboard of greater than 90 degrees. 13. A pen-based computing system comprising: a tablet unit comprising: a processing component and a display component including a digitizer to capture data entered with the pen and housed within an enclosure; a base unit comprising: a first and second panel connected by a flexible hinge; wherein the first panel has a generally flat body having a keyboard and at least one longitudinal track complementary to at least one wheel rotatably mounted to the enclosure of the tablet unit, thereby to check sliding motion of the tablet unit relative to the first panel when the tablet unit is supported by the first panel so that it makes an acute angle therewith; wherein the flexible hinge comprises a curved portion extending into the second panel; wherein the second panel is in contact with the tablet unit in the said acute angle with the first panel; wherein the curved section of the hinge is coplanar with the bottom surface of the first panel; wherein, when in a viewing position, a load from the tablet unit is directed through the second panel to the hinge, wherein the bend in the curved section of the hinge disperses some of the load acting on the hinge away from the first panel. 14. The system of claim 13, wherein each longitudinal track comprises a plurality of teeth to mesh with complementary teeth of each of the wheels rotatably mounted. 15. The system of claim 13, wherein the tablet unit further comprises a braking mechanism to check the free rotation of the at least one wheel. 16. The system of claim 15, wherein the braking mechanism comprises a braking element in frictional contact with the at least one wheel. 17. The system of claim 16, wherein the braking element includes a spring biased to bear against the at least one wheel. 18. A pen-based computing system comprising: a tablet unit comprising a display screen, a digitizer to capture data entered with the pen and an electronic assembly housed within an enclosure; and a separate base unit including two panels connected via a hinge positioned at an edge of each of the two panels' coupling points to one another, a first one of the panels bearing a keyboard, and a second one of the panels being displaceable relative to the first panel to prop the tablet unit in a viewing position in which the display screen makes a viewing angle with the keyboard of greater than 90 degrees, wherein the tablet unit and the first panel have complementary formations to prevent sliding movement of the tablet unit relative to the first panel when in the viewing position; wherein the first panel has a generally flat body including a keyboard and at least one longitudinal track shaped and dimensioned to receive a rotatable member of a tablet unit, whereby the tablet unit is supported by the first panel so that it makes an acute angle therewith; wherein the hinge is flexible and comprises a curved portion extending into the second panel; wherein the curved section of the hinge is coplanar with the bottom surface of the first panel. 19. The system of claim 18, wherein the complementary formation of the tablet unit comprises at least one wheel rotatably mounted to the enclosure of the tablet unit. 20. The system of claim 19, wherein each wheel includes a plurality of teeth. 21. The system of claim 19, wherein the tablet unit further comprises a braking mechanism to check the free rotation of the at least one wheel. 22. The system of claim 21, wherein the braking mechanism comprises a braking element in frictional contact with the at least one wheel. 23. The system of claim 22, wherein the braking element includes a spring biased to bear against the at least one wheel.
