The Balt Web A/V Cart, Model 85052 (Black) is great for use as a stand-up workstation or A/V cart.
This cart is a fine choice for speaker support. Its streamlined design and mobility allows the speaker to place the cart wherever it is convenient. It won't block his/her vision of the audience, yet gives the freedom to run a projection show from the cart.
