Head phone
I want a phone small enough to fit somewhere inside my skull. Plenty of room there. Or even a dental implant. Kinetic charging from chewing gum. Siri to whisper the time in a sexy voice. Built-in heart-rate blood pressure and steps monitor. Satnav. Fuck this is a good idea. In fact several implants linked by - what else - blueteeth. Phew! Now I have seen the future 50 years hence I need to lie down and listen to War and Peace.
Oh not finished. Direct link to the optic nerve so no external display. Do not disturb I am watching Star Wars Part Soixante-Neuf.
