My point was "their system's hardware specifications" is, for some popular
vendors, a *very* fuzzy notion. You can't (for instance) say "specs are
available for a Dell Latitude D820" - there are configurations that specs are
available for, and configs that aren't.  My D820 has an NVidia card in it - we
know the answer there.  Do you give a different answer for a D820 that has the
Intel i950 graphics chipset instead?

Even more annoying, Dell often *changes* the vendor - the line item for the DVD
drive says "8X DVD+/-RW" (other choices include 24X CD-ROM and 24X CD-RW/DVD).
Mine showed up with a Philips SDVD8820 - but it's possible that some other D820
will get some other vendor's DVD (I've seen 2 C820's ordered at the same time,
they showed up with 2 different vendor's "24X CD-RW/DVD").  It's possible that
some poor guy is going to get a D820 that has a DVD that we have a known
buggy driver for - what do we tell *them*?

It's *easy* to do a "semi-good" that tells you if there's drivers for the
hardware config you're running the program on. But there's 2 problems:

a) You probably already know the answer
b) By the time you can run the program, it's often too late....

So given those 2 points, what actual value-added info does this *give*, over
and above 'lspci' and friends?  I suppose maybe for a install CD, it gives
a quick way to cleanly abort the install with a "Don't bother continuing
unless it's OK that your graphics/wireless/whatever won't work".  On the
other hand, the installer should have a grasp on this *already*....

Perfect may be the enemy of the good, but the good is also the enemy of
stuff claiming to be good but misses on an important design goal...
