The future of speedy paper-thin tablets running Intel's Broadwell chips seems promising, after we tested the first-ever prototype shown by the chip maker. We got an exclusive hands on, albeit for a short while, with a paper-thin tablet called Llama Mountain, which ran on an as yet unreleased fifth-generation Core processor, at the Computex trade show in Taipei. The tablet was fully operational and running Windows 8, and it wasn't the typical dummy unit often shown at many press conferences.
