No, lovable Pixar character Wall-E hasn't been viciously beheaded. You're looking at Etón's first portable, sun-powered Bluetooth sound system. The Rukus Solar, which features a built-in high-efficiency monocrystal panel, debuted last week at CES. But why was it being shown at the E Ink booth at the ShowStoppers press event?

As you'll see more and more, E Ink isn't just for e-readers. Rukus Solar uses a SURF (Segmented Ultra-thin Rugged Flexible) display for its durability, readability in sunlight and low power requirements. So as you catch rays and charge your music player (safely tucked away in Rukus' handy little built-in cargo pouch), you can listen to 14 watts of stereo sound that much longer.
