the cart further comprising an input device, the input device configured to receive a user identifier, the user identifier being associated with a user height;

said accessory cart having stored thereon a series of predetermined heights, each of the stored predetermined heights being associated with at least one user height,

whereby said accessory cart is further configured to receive a user identifier from the input device and to adjust the housing element, using automatic non-manual means, to position the housing element at the predetermined height associated with the user height that is associated with the received user identifier.

2. The accessory cart of claim 1 where the user height is a height for a standing user.

3. The accessory cart of claim 1 where the user height is a height for a sitting user.

4. The accessory cart of claim 1 further comprising a series of casters attached to the base, and a tracking wheel attached near the center of the base.

5. The accessory cart of claim 1 where the input device comprises a wireless communication device adapted to wirelessly receive the user identifier.

6. The accessory cart of claim 1 wherein the user identifier comprises a user height.

7. The accessory cart of claim 1 wherein the user identifier comprises a user login identifier.

8. The accessory cart of claim 1 wherein the user identifier comprises an access identifier.

9. A method of adjusting a height of a platform of an accessory cart, said accessory cart comprising a base, an adjustable housing element connected to the base, and a work platform connected to the housing element,

the accessory cart further comprising an input device, a computer processor and computer memory;

said computer memory having stored thereon a series of predetermined positions and user identifiers, each user identifier associated with at least one user height,

each of said series of predetermined positions being associated with at least one user height,

said method comprising the steps of:

said processor receiving a specified user identifier from the input device, where the user identifier is associated with a predetermined position;

said processor receiving, from the computer memory, the specific predetermined position associated with the user identifier; and

using the specific predetermined position to move the adjustable housing element by automatic non-manual means to thereby move the work surface to a height associated with the specific user's user height.

10. The method of claim 9 where the predetermined position is associated with the height of a standing user.

11. The method of claim 9 where the predetermined position is associated with the height for a sitting user.

12. The method of claim 9 wherein the accessory cart further comprises a monitor positioned above the worksurface.

13. The method of claim 9 where the input device comprises a wireless communication device adapted to wirelessly receive the user identifier.

14. The method of claim 9 wherein the user identifier is a user height.

15. The method of claim 9 wherein the user identifier is a user login identifier.

16. The method of claim 9 wherein the identifier is an access identifier.

17. An accessory cart, comprising:

a base;

an automatically height-adjustable housing element connected to the base, said housing element extending upward from the base;

a work platform connected to said housing element,

said accessory cart further comprising

a computer processor and computer memory, and an input device, the input device configured to receive a user identifier, where the user identifier is associated with a predetermined ergonomic height of the work platform stored in said computer memory based on the user's height;

whereby said accessory cart is

further configured to receive a user identifier from said input device and to automatically adjust said housing element to position said work platform at the predetermined ergonomic height.

18. The accessory cart of claim 17 further comprising an electronic access card readable by the input device, where the electronic access card has stored thereon one of said user identifiers.

19. The accessory cart of claim 18 wherein the electronic access card is wirelessly readable by said input device.

20. The accessory cart of claim 17 wherein said association between said user identity and the predetermined ergonomic height of the work platform is contained in a database in said computer memory.

21. The accessory cart of claim 18 wherein said association between said user identifier and the predetermined ergonomic height of the work platform is stored in said access card.

22. An accessory cart, comprising:

a) a base;

b) a height-adjustable housing element extending upward from the base;

c) a work platform connected to the height-adjustable housing element; and

d) an automatic height adjustment mechanism operatively connected to the work platform for automatically adjusting a height of the work platform, the automatic height adjustment mechanism comprising an input device; a computer communicatively coupled to the input device; and a motorized lift operatively coupled to the computer;

wherein the input device is configured to receive a user identifier from the input device, said user identifier having height information of a user associated therewith, and wherein the computer is configured to communicate with the motorized lift to cause the height of the work platform to automatically adjust to a predetermined height associated with the height information of the user.

23. The accessory cart of claim 20 wherein said computer memory is located remotely from said base, said housing and said work platform.

24. The accessory cart of claim 17 wherein the predetermined ergonomic height of the work platform is based on the user's standing height.

25. The accessory cart of claim 17 wherein the predetermined ergonomic height of the work platform is based on the user's seated height.

26. The accessory cart of claim 17 wherein the predetermined ergonomic height of the work platform is selectable between the user's standing height and the user's seated height.

27. The accessory cart of claim 22 wherein said input device is a control panel.
