To answer Bill K’s original question, I overall prefer when the industry uses the same cables for daily, common tasks such as physical connections for data/charging. Interchangeability helps prevent waste and allows for greater versatility.
Look at USB. When Mac/Windows/Linux/Unix systems moved to USB it opened a floodgate of options that did not require converters and custom dongles. Everything connected the same way and it only improved when more devices cooperated with common driver standards (where possible). I can connect almost any mouse, keyboard or black & white laser printer via USB and be working almost instantly. Granted, the extra features on a printer may not function with out extra software, but I can print a document very quickly.
That being said, the Lightning connector does have a couple advantages over USB-C:
- Smaller connector – Allows more space to do other things in small devices (ie. phones). A little more space can go a long way when you are trying to cram in sensors, battery and other things. Granted, this is not a big difference, but in pocket devices every mm counts.
- Easier to clean – Lightning cables have just a tab. The socket is much easier to clean because it is essentially a hole. I have successfully cleaned them (carefully) with a toothpick to get the lint out. This is not remotely as easy with USB-C because the hole has a thin “card” in the center that could break. Additionally, with USB-C, both the cable and socket have a hole that can collect dust and debris. With Lighting, the exposed contacts can even be cleaned if they get a little dirty. Of course, the soiling is more likely to happen due to it being more exposed to touching and other contact.
So with out a lot of data on failure rates and longevity, the Lightning connector appears to win just in the category of physical maintenance.
Beyond that, USB-C “wins” just about every other category.
