Jeans with an in-built 'laptop' computer The creation comes with a full-size blue tooth keyboard and also features integrated speakers and a wireless computer mouse. The duo hand-stitched the prototype trousers - dubbed 'Beauty and the Geek' - which are designed to give the user the freedom to move around and still be in control of the computer. The invention works using a USB device which plugs into the computer port maintaining a wireless connection. According to de Nijs the trousers are only slightly heavier than normal jeans and are expected to sell for just over £250 if they make it to the market.
