So there is currently an argument about whether a question that involves mobile data usage on a computer is off-topic or not. I don't quite understand why that makes it a "mobile device" question (besides the exemption for "interfacing with a computer", my impression was that questions specifically had to be about mobile OSes such as Android in order to be offtopic).

(The question in question is https://superuser.com/questions/1439188/free-mobile-data-when-using-%C2%B5torrent.)

So I thought I'd ask for a clarification for this particular edge case (a question that's about a computer program and mobile internet connection)... using a list of hypothetical posts:

1. Something happens on a computer.
2. Something happens on a laptop.
3. Something happens on a laptop which just happens to have a 4G modem built in, or a computer which just happens to have a USB 4G modem connected.
4. Something happens on a laptop while it is using its built-in 4G mobile data connection, but not while it is using Wi-Fi/Ethernet.
5. Something happens on a laptop while it is using a phone-tethered mobile data connection, but not while it is using regular Wi-Fi/Ethernet.
6. Something happens on a laptop while it is using Wi-Fi/Ethernet, but said Wi-Fi is provided by an external 4G mobile data modem.
7. Something happens on a phone while it is using mobile data connection, but not while it's using my home Wi-Fi.
8. Something happens on a phone.

(I'm writing this while still half-asleep.)

Here #1 (and hopefully #2-#3) aren't offtopic, #7 is IMHO on the edge, while #8 is generally offtopic. What about the rest? In particular, would #4 and #5 be considered offtopic, and are they the same level of (not-)offtopic or do they get different rulings? (Although honestly I'd be even more confused if they got ranked differently – either they're both on-topic because PC, or both are off-topic because mobile data.)
