Well, it does it for multiple platforms, which is an issue for me.
It does it in a relatively platform-independent way.
It is also capable of depicting such things as disk partitioning, which
would be an extremely useful adjunct to full backups for contingency
planning, especially since it can to this automatically -- thus removing
an element of human fallibility.
Further, dmesg output includes various kernel messages that are, at
best, extraneous for this particular exercise.
There is also information reported which is (admittedly) of little
interest for contingency planning, but which may well be of interest for
someone hacking software, such as:

(I hand-edited some of that to make most things fit reasonable line
lengths....)
Basically, it provides one-stop shopping for a lot of information that
can be useful, especially for resolving weird hardware or configuration
problems.
One of the main reasons I'm interested, aside from contingency planning,
is that I am (still) very unfamiliar with PC hardware, and I need to
support systems that already exist, and for which little or no hardware
docs may be available.
And I'm not willing to even seriously consider using something that
"runs" (to abuse that term) in a Microsoft environment to diagnose, fix,
or configure anything; the perception that a Microsoft product is
appropriate for something important is, in my opinion (only), a symptom
of a far deeper problem.
Oh: The above "sysinfo -level all" excerpt was from an Axil box running
Solaris 2.5.
Cheers,
