It's called HAL (Human Assistive Limb) and it will cost you $4500 starting from October. Developped by Cyberdine (the real one, not the Terminator fantasy) it has already started to show up on Tokyo streets. HAL is about 25kg in weight but will boost your muscle power upto 10 tiger more so you can run around, carry groceries and beat the crap out of that bully effortlessly. As glorious as the future looks on exo-skeletons, I see a lot of people getting addicted to laziness artificial muscles will offer.
