Just lost me.
> you are only supposed to interact with it by running it and typing commands
So, "the last computer you'll ever need" ... other than my phone, because the last time I wanted to type commands on a phone-sized device, was back when I was wet-dreaming over the Sharp Zaurus.
Given the artificial scarcity of the IDs and the semi-mystical woo describing the proposition, my spidey-sense is telling me some smart people have been busy devising an naivety-magnet, all the better to part people from their money ("buy a planet"...um, ok).
You can also generate a comet, which is effectively identified by the hash of its public key. Those are free; while eventually planets have some notional advantages, notably a default positive reputation, at the moment there are no downsides.

Re command line: I was based it off the public docs. Go to "https://urbit.org", click on "install". The very end of the instructions say:
> Type (add 2 2) into the Dojo.
Maybe "install" is wrong section? I went to "docs" instead, from that "operators manual" seems most user-friendly. But it is text only as well:
> Let's join the ~dopzod/urbit-help channel. Use ctrl-x to switch from the Dojo prompt to the Chat prompt. Then:
> ~sampel-palnet:chat-cli/ ;join ~dopzod/urbit-help
The only reference to web UI I found was in "Using Bridge" section, but that seems a pre-requisite to set up the system, not part of the system itself.
If there are web UIs, you really need to document them better. Some screenshots would be great, for example.

From the practical standpoint, you have a linux process running from a data directory. You run it, and the you can access it via CLI and via web interface (which also has a terminal-like webapp). It then uses regular IP to talk to other urbits in P2P fashion.
From what I could find, the whole thing is full of magic and pretty opaque - you are only supposed to interact with it by running it and typing commands there. In particular, you’d probably want to back it up. The only instructions I could find is to stop it and tar it up, and back up manually. Better do it often if you want your “digital life” to be safe.
