We’re in thet awkward phase where it appears that USB-C is the future but there are a lot more computers out there with USB-A and no USB-C ports than there are with USB-C and no USB-A.
There’s also the consideration that the technical advantages of USB-C are somewhat limited in a device like the 4C. Obviously there’s size but it’s not like a C-connector is going to save a significant amount of rear panel space relative to a B-connector.
At first, I assumed PD would be an advantage but the more I thought about it, it was a mixed bag. While bus power is theoretically possible, in reality, how many computers out there can push 27W to a bus-powered device? That’s almost as much power as my laptop’s power supply provides! The one major advantage of USB PD is that it would open up a whole range of power supplies relative to those supplying 9V @ 3A with a barrel connector.
While we always like more bandwidth, the reality is that control signals and audio in a device like this wouldn’t even saturate USB 2 so USB-C’s potential would go untapped.
Given the number of peripherals that don’t stand to benefit from USB-C’s technical advantages, I’m wondering if we’re likely to see USB-A connectors for several more years despite the benefits of USB-C, at least until the cost of the interface becomes a financial no-brainer for manufacturers.
