Let me have a go at the current rules of:

> **In:** computer hardware, computer software, or personal and home computer networking.
>
> **Out:** electronic devices, media players, cell phones or smart phones or game consoles, except insofar as they interface with your computer.

I would suggest something like:

> **In:** Computer technology and computer hardware, software, networking and
> auxiliary devices, for the purpose of improving understanding, usage,
> or just making things work.
>
> **Out:** Special-purpose electronic devices such as media players, phones
> and game consoles,
> except when networked to computers or running a general-purpose operating
> system (such as routers or Embedded Windows).

Note:
Judging by the number of upvotes on the post, I'm not the only one that
finds the rules somewhat confusing.
This is just a first try that I'm putting up. I'm not asking here for
a vote on including it in the help, as that's for the moderators,
so **there is no point in downvoting**.
Criticism or suggestions would help.
It's very difficult to phrase a rule that is both general and precise
at the same time.
