Reversible Type-C USB Connector Ready For Production 191
orasio writes: One of the most frustrating first-world problems ever (trying to connect an upside-down Micro-USB connector) could disappear soon. The Type-C connector for USB has been declared ready for production by the USB Promoter Group (PDF). "With the Type-C spec finalized, it now comes down to the USB-IF to actually implement the sockets, plugs, cables, adapters, and devices. The problem is that there are billions of existing USB devices and cables that will need adapters and new cables to work with new Type-C devices. It’s a lot like when Apple released the Lightning connector, but on an even grander scale. Further exacerbating the issue is the fact that China, the EU, and the GSMA have all agreed that new mobile devices use Micro-USB for charging — though it might be as simple as including a Micro-USB-to-Type-C adapter with every new smartphone."

Please keep in mind an important aspect of this new cable, it supports 100 watts power transfer. That means most devices, including laptops, can be charged through this one connector. I see that as the best reason to switch, fast charging and universal connector for all my devices. The article glosses over that important detail. It also enables 10 Gbs data transfer.

There's even more to it than that. The typical 3.5mm *will* briefly short when mating. Not that this is necessarily a problem but it needs to be taken into account in the design.
Furthermore USB being a high speed data link relies on transmission line characteristics. That is the impedance of the lines need to be carefully controlled, the distance between data lines needs to be carefully controlled, and in these cases the construction of the connector matters a lot. Everything from the spacing of the pins to the shell, to the layout of signals as they reach the circuit board matters. There's no easy way to keep this all nice and even if you pass one signal through another.

The magsafe plug was probably deliberately left off that list, because the first iteration was a safety risk, and came with a special instruction sheet to plug / unplug it so that it doesn't burn down your house.
