The term “substantially” refers to an amount of something that is considerable or significant, even if it is not necessarily complete or absolute. For example, the arm 108 of the presentation stand 100 shown in FIG. 1 extends substantially upward from the base portion 106 of the presentation stand 100 because the arm 108 is mostly pointing upward, although the arm 108 is not fully oriented in a vertical direction. In some embodiments, a device member (e.g., the arm 108 of the presentation stand 100 shown in FIG. 1) may be said to be extending substantially upward (or extending upward in a substantially vertical direction) if at least some portion of the device member is oriented within 1° of a vertical direction. In other embodiments, a device member may be said to be extending substantially upward if at least some portion of the device member is oriented within 10° of a vertical direction. In still other embodiments, a device member may be said to be extending substantially upward if at least some portion of the device member is oriented within 30° of a vertical direction.
