A portable workstation includes wheels, a tabletop, a generally planar member and a chassis joining the wheels, the tabletop and the planar member. While joined to the wheels and the tabletop by the chassis, the planar member is movable between a protracted position and a retracted position. A majority of the planar member extends above the tabletop in the protracted position, and a majority of the planar member does not extend above the tabletop in the retracted position.

1. A portable workstation, comprising: a. wheels for movement of the workstation;b. a tabletop providing a work surface for the workstation;c. a generally planar member; andd. a chassis joining the wheels, the tabletop, and the planar member, the chassis comprising the three dimensional support frame defining a shelving structure upon which a drawer is received and supported;e. wherein, while joined to the wheels and the tabletop by the chassis, the planar member is moveable between, i. a protracted position, wherein a majority of the planar member extends above the tabletop, andii. a retracted position, wherein a majority of the planar member does not extend above the tabletop;f. wherein the drawer is disposed in sliding engagement with the support frame between an open position and a closed position; andg. wherein the planar member and the drawer are configured such that the planar member secures the drawer from moving from the closed position to the open position when the planar member is in the retraced position and the drawer is in the closed position; andh. wherein the tabletop defines the entire top surface of the portable workstation and includes therein a slot through which the planar moves when moving between the protracted position and the retracted position. 2. The portable workstation of claim 1, further comprising a lock moveable between a locked position, wherein the planar member is inhibited from moving from the retracted position to the protracted position, and an unlocked position, wherein the planar member is allowed to move from the retracted position to the protracted position. 3. The portable workstation of claim 1, further comprising a biasing member that biases the planar member in a direction from the retracted position toward the protracted position. 4. The portable workstation of claim 1, wherein access to the interior of the drawer is inhibited when the planar member is in the retracted position. 5. The portable workstation of claim 1, the drawer is removable from the support system when the planar member is in the protracted position. 6. The portable workstation of claim 1, wherein the planar member comprises a display surface. 7. The portable workstation of claim 1, wherein the planar member comprises a display surface on each of oppositely facing sides thereof. 8. The portable workstation of claim 1, wherein the planar member comprises a dry erase board. 9. The portable workstation of claim 1, wherein the planar member comprises a chalk board. 10. The portable workstation of claim 1, wherein the planar member pivots about a pivot axis between the retracted position and the protracted position. 11. The portable workstation of claim 1, wherein the pivot axis is orthogonally disposed to the plane of the planar member. 12. The portable workstation of claim 1, wherein the tabletop is removably joined to the support frame such that the tabletop may be replaced with the different tabletop. 13. The portable workstation of claim 1, further comprising a handle for facilitating movement of the planar member between the protracted position and the retracted position. 14. The portable workstation of claim 1, wherein the drawers of the workstation may be insulated. 15. A portable workstation, comprising; a. wheels for movement of the workstation;b. a tabletop providing a work surface for the workstation;c. a first generally planar member;d. a second generally planar member; ande. a chassis joining the wheels and the tabletop to the first and second planar members, the chassis comprising a three-dimensional support frame defining a shelving structure upon which a first plurality of drawers is received and supported on a first side of the chassis and a second plurality of drawers is received and supported on a second side of the chassis;f. wherein, while joined to the wheels and the tabletop by the chassis, the first planar member is moveable between, i. a first planar member protracted position, wherein a majority of the first planar member extends above the tabletop, andii. a first planar member retracted position, wherein a majority of the first planar member does not extend above r the tabletop, and wherein the first planar member secures the first plurality of drawers each from moving from a closed position to an open position; andg. wherein, while joined to the wheels and the tabletop, the second planar member is movable between, i. a second planar member protracted position, wherein a majority of the second planar member extends above the tabletop, andii. a second planar member retracted position, wherein a majority of the second planar member does not extend above the tabletop, and wherein the second planar member secures the second plurality of drawers each from moving from a closed position to an open position. 16. The portable workstation of claim 15, wherein the first planar member pivots in a first rotational direction in moving from the first planar member retracted position toward the first planar member protracted position, and wherein the second planar member pivots in a second rotational direction, opposite to the first rotational direction, in moving from the second planar member retracted position toward the second planar member protracted position.
