My Mac Book Pro (from early 2009) worked off of a cheap-O  12V cigarette 
lighter 150W Mod Sine
inverter while driving to MREF from Minnesota last year (I was in the 
back seat)....  That is,
until we stopped for lunch and battery voltage dropped.

When we came back out of  the restaurant, the inverter was dead.   The 
battery voltage dropping is
the only thing I can think of that would have killed it.

I also seemed to notice that the Apple power supply got quite a bit 
hotter when running under
this waveform.  Not sure how much hotter exactly.

That's one experience.
