The references to runlevels are a bit strange, as they are not defined by the kernel and the Debian system doesn't distinguish runlevels 2-5 either (it's left to the administrator).

I'm pretty sure that the reference to runlevels is a shorthand for how much he's gotten to work. So the runlevel 3 on his Atom machine means he has tested networking but not X11, while runlevel 5 on the Macbook means he can run X11.

Despite the fact that many people list runlevels with these meanings, in Linux it's just a convention used by some people and not intrinsic or a commonly accepted rule. I boot to runlevel 2 always, because higher numbers are ostentatious.

Yeah it's kinda stupid that in Ubuntu, which uses the "rl 2" semantics, you can't deactivate network by changing to another rl.

You certainly can, you just need to configure a runlevel of your choice to work that way.

The average user can figure out how to change runlevels. The average user is going to stumble attempting to configure a custom runlevel.

The average user will either unplug the ethernet cable, or click on the NetworkManager applet, instead of mucking with their runlevels at all.

The average user in my household has never heard of "runlevels"
