Windows 8 has survived for testing only 1 hour. After Ubuntu 14:04 was quickly installed. All components work out-of-the-box. The graphics card is stable with the open source driver. Too bad that this device is not available without an operating system. Only, the sound is a bit tinny. Despite various settings using equalizer were from the speakers hardly depths to tickle out. The speakers were then overwhelmed and began to buzz. But otherwise the device is fast, has a super graphics and long battery runtime.
