I do. I use it in my Gear VR headset. Changing to Type C would mess that all up. It was always forecast when they released Gear VR with the old Micro USB connection.
I have a phone with USB-C (Nexus 6P), and while I do appreciate the ergonomics of the new plug (it both feels more secure while being less awkward to insert/unplug), the lack of compatibility is a huge drawback. I have to be sure to always carry my own cables with me, and there are no wireless charging dongles that use USB-C. So if you go to Starbucks and want to make use of their Qi charging pads, you're SOL.
We would use it for something else if it were able to do something else..
On the other hand, you can now find a nice system (Harmony Hub from Logitech) that acts as powerful IR blaster inside your cabinets (and with a small emitter that you can also place directly on your TV's receiver) and you use your smartphone to zap, change volume etc via WiFi... it works like a charm and you don't need to point at the devices anymoreStill no IR. Phones make handy remotes...but not if they can't talk to your components.
