Want to boost your iPad's meagre 64GB SSD to a man-sized 500GB hard drive? Seagate has just unveiled the world’s first wireless external hard drive. The 500GB GoFlex Satellite has a built-in battery and Wi-Fi that allows you to connect to up to three devices at once, be they tablets or smartphones. The battery lasts 25 hours in standby and 5 hours in use. Your mighty 64GB iPad can grow to an epic 500GB for an unconfirmed £120 – better invest in a bigger bag too.
