I love the idea of having USB-C sockets around the home, with the occasional traditional socket - strategically placed, for the heavy duty appliances. It's nice to imagine a future where we don't have to carry PSUs around with us because we are able to plug our electronic devices directly into the wall with a single, standardised USB-C cable. Imagine how much pain this would take out of international travel too. Of course, the costs of upgrading all those billions of sockets would be huge and who knows how long it will be before the next iteration of USB arrives - making our USB-C sockets obsolete?
