Yesterday, Apple announced the new MacBook, with a 12-inch Retina display and a body so thin it can only accommodate a single USB Type-C connector alongside a 3.5mm audio jack. That's it: the single USB connector is used for both charging and data throughput.
As there is only one main port on the new MacBook, you're probably going to need an arsenal of adapters to connect up your peripherals, displays and more. Apple's got you covered in this department, offering a range of rather expensive adapters to bring back the ports from their older laptops.
The first adapter is basic, going from USB Type-C to standard USB in a $19 cable. If you want to use more than one device at a time, you'll need one of Apple's Multiport Adapters, which retail for $79 each. One of these adapters features a single USB port, HDMI, and USB Type-C for charging, while a variant swaps out HDMI for VGA.
If you want to attach more than one USB device, or plug in an SD card, or attach a Thunderbolt device, you'll need to purchase another adapter from a third party. If you want to charge the new MacBook while pushing video out to a display, you'll need to fork out the $79 for the Multiport Adapter until a non-official alternative appears.
To many people, having to carry around a selection of adapters on the off-chance you'll need to plug something in is pretty inconvenient. To others, the super-slim 13.1mm body of the MacBook is worth the trade-off in connectivity.
