The document summarizes an presentation on the E-Ball, a spherical computer designed by Apostol Tnokovshi. It is the smallest PC ever made, with a 6 inch diameter sphere containing a 120x120mm motherboard. It projects a keyboard and display using an LCD projector. The E-Ball has features like a wireless optical mouse, 350-600GB hard drive, 5GB RAM, and can use any flat surface like paper as a display screen. While portable and powerful for presentations, its high cost and incompatibility with normal operating systems are disadvantages. The concluding statement is that as technology advances, computers continue to shrink in size.
