my implication was that if you're flying "hard IFR", you're in IMC on
an IFR flight plan, and would thus be subject to 91.21.

91.21 applies to all flight. If you think that WxWorx with a laptop is not
legal for "hard IFR" (which most of us call "hard IMC") based on 91.21, then
you think it is not legal under any circumstances. Do you really think
that?

I, and many pilots I know, interpret this rule to mean that flying
under part 91 on an IFR flight plan, it is illegal to use any portable
electronics not FAA-approved. This rule says nothing about VFR
operations. I think the issue at hand is if you are in the soup and
using an 'unapproved' piece of electronic equipment that you really
don't know for certain will or won't cause interferenec with your
equipment, then you shouldn't be using it. Another idea may be that
if you are fiddling with a laptop sitting in your lap, right seat or
even a pedistal between seats, that's time that you're not focused on
the instruments.
