Is there a good all-or-many-in-one dongle with several USB or other ports?
Are the any options for extra power supplies?
Is there a good dock for using it with a big display on a desktop?
After struggling for a few years trying to use dongles I'm actually becoming convinced such a thing might not be possible. My screens flicker, my drives drop out all sorts of issues no matter what the dongle or the devices.
The other thing that points to this is the fact Apple doesn't just sell one, they could easily sell a USB-A/Display port/Power dock for around $400 and people would lap it up but curiously they don't because I think deep down they have realized the only reliable way to use a USB-C port is a one to one conversion.
If you happen to buy a 2019 macbook pro, then don't worry with that, just type on the silicon keyboard cover. It will be bad, but not as bad as using the actual keyboard directly.
