Enter the Signature Touch, the new flagship smartphone from English luxury manufacturer Vertu. With acoustics tuned by Bang & Olufsen and a camera certified by Hasselblad, it's a cut above the rest when it comes to sound and vision, not to mention a scratch-proof sapphire crystal screen casing that's impervious to anything but diamond. The price to pay to have what's essentially a scaled down cinema in your pocket? £6,750.
