This week the folks at Apple have revealed the new MacBook, a notebook with just 2 ports. One is for your headphones - a standard headphone jack that also allows mic-in. The other port is a USB-C, a sort of "universal" port which allows you to charge the notebook up as well as run video out and peripherals in. To make use of this port for power, you won't have to do anything special - there'll be a power cord in the box. For everything else, you're going to have to pay a little something extra.
