Just a thought. The new USB-C port is so versatile but Lightening has been always versatile too. There are a lot of adopters that turn the Lightening port into HDMI, USB, and so on. Apple has been using Lightening for years already, and it's very popular now. There are Lightening storages, batteries, cameras, etc. When Apple unveiled the MacBook, I thought maybe Apple had decided to go with USB-C to replace Lightening, but it turns out Apple still uses Lightening for their new products like their keyboards, trackpad, and AirPods. If they don't completely switch to USB-C, the benefit of having a USB-C port on the MacBook is limited. You still need to have different cables and dongles. If the only port was Lightening instead of USB-C, you could have a universal charger for all of your Apple devices, charge your Appel Pencil with your MacBook, use the Lightening EarPods with your MacBook, etc. Plus, the Lightening connector is better designed, I think. It is little smaller than the USB-C connector, and much easier to plug in and out. What's your thought?
