In order to make laptop models as light as possible, Intel is trying its hand at fabric cases as seen on the "Twin River" prototype showcased at Computex this year. The fabric case is made of polyester, polyamide plus lycra, and it integrates a dual-display setup with 1080p touchscreens that can be used as a book / notepad or regular laptop mode with one screen acting as a touch keyboard.
