The document describes the E-Ball, a spherical computer that is the smallest PC design. Measuring 160mm in diameter, the E-Ball contains all the components of a traditional computer, including a motherboard, hard drive, web cam, and more. It has a wireless optical mouse, virtual keyboard, LCD projector, 350-600GB hard drive, and is powered by pressing buttons on the sides. While portable and high performance, it also has high costs and potential difficulties with hardware issues. The E-Ball represents how computer technology is pushing boundaries to create increasingly compact devices.
