Yes.
Yes.
2. Why throw away something that is perfectly working and useful?
It’s not so simple to migrate. Consider:
- Some devices have a proprietary end and a USB-A end, and there’s no USB-C equivalent (my Pebble chargers; my microphone; my webcam). I have tried dongles with these before and left disappointed every time
- some devices have a USB-A cord attached permanently, such as my desk lamp. Again, dongles are unreliable here and thus a downgrade.
- For portable devices like my standalone GPS for bike touring, my lights for my bicycle, my phone, my watch, and anything else small I might want to charge when travelling by car… I still need USB-A for the car itself. Easier to pack one cable for the whole trip instead of a USB-C cord for hotels and a USB-A cord for the car.
- My personal laptop still has USB-A ports, but no USB-C ports. As far as I can tell there are no non-sketchy adapters that go from a male USB-C cable to a female USB-A port. Apple makes a very expensive Thunderbolt2<->Thunderbolt3 adapter that I use at my desk when I want to use my personal laptop there, but that adapter is $50 or so. Already over your budget.
- I don’t have any USB-C wall warts at all. The last phone I bought was the 2016 iPhone SE. I have a plethora of USB-A wall warts from family and friends who didn’t need them. They work well.
Why are some people so hellbent on removing functionality that other people use every day and can’t replace without significant expense and inconvenience? It’s just like the damn headphone jack on iPhones: I understand that a lot of people are fine with Bluetooth only, but I am not. It’s frustrating to lose the option.
I imagine you were outraged when laptops started replacing serial ports with USB-A, too.
I love USB-C on my phone and think it's a great upgrade, but I'm not interested in contributing to more e-waste to upgrade a laptop that doesn't need it, just so I can buy more ultimately e-waste adapters with USB-C.
For me, the best thing about USB-C on a laptop is universal charging. That's been a game changer.
USB-C just doesn't have many benefits over USB-A for a huge number of peripherals and cables. It's useful for bandwidth for one webcam I own, but for my mouse, my keyboard, my e-reader, and most other devices... there's no difference other than the cable shape. It's enough of a sidegrade (and enough of a pain in the ass to deal with adapters) that it just isn't worthwhile. And, as I said -- backwards compatibility is a big issue for me, since my personal laptop only has USB-A/Thunderbolt 2 ports.
Not to mention the fact that my raspberry pi 4, which I'll be using as a lightweight home server for years, only has USB-C for power input... USB-A for all other peripherals. A minority of devices in my household (only one!), between my personal laptop, work laptop, home server, car, and wall warts, use USB-C. Upgrading would require a lot of inconvenience and redundancy.
