I'm incredibly excited for the possibilities of this connector. Imagine a laptop that has a bunch of USB Type-C ports—and nothing else. Plugging a (universal!) charger into any of them charges the laptop at a rate of up to 100 watts. Displays are connected via DisplayPort-over-USB, etc. In fact, the display could actually be the charger as well (or, if you have a desktop, the display could be powered from the PC). A single USB Type-C cable could run an all-encompassing, manufacturer-agnostic docking solution.
Phones would also feature the same connector, so a laptop charger could also charge a phone, with no adapter needed.
I'm really looking forward to having a single connector for virtually all of my devices (excluding special situations, such as water-resistant devices) within the next few years.
