But that's exactly where live view is better than an optical
viewfinder -- it shows you what the actual *sensor* is seeing, not just
what light is coming through the lens. (Also it can be boosted so you
can see in light you couldn't see in optically.)
It also shows you 100.00% of the image, much more accurately than an
optical system can (and many optical viewfinders don't even try for
100%).
A pivoting LCD can also let you see the viewfinder from a much wider
range of angles.
Using a tripod isn't always possible. Shooting in a club or late-night
jam session is the sort of thing I do where a tripod isn't usually
possible, and mirror slap (and any other source of vibration) is a
serious issue. And tripods don't always solve the problem at
intermediate speeds -- 1/8 or 1/4, say, depending on resonant
frequencies.
They're smaller and lighter than DSLRs, and much more capable than P&S
(also smaller than some of them).
The biggest weakness (and they're clearly working to correct this; see
what Nikon says about their 1 series and Fuji about the latest Pro model
and Olympus about the OM-D) is AF speed and tracking, which you didn't
have at all with many of the SLRs you used (none of the ones you
mentioned have AF). M43 has less good low-light performance than
exceptional cameras like the D700, but they're competitive with DSLRs in
their price range.
