[Leica] Why Micro-4-3rds?

[drodgers at casefarms.com (David Rodgers)]

I bought a GF-1 because it seemed the most economical way for me to be
able to use some of my existing lenses -- which quite frankly were
gathering dust -- as well as replace a 5-year old Fuji P&S. 

Micro Four Thirds is better than I anticipated and it has rekindled my
interest in photography. I'm sure an EP-2 would have done the same.  

The image quality from micro Four Thirds format is pretty darn good.
Where it's lacking, compared to an FX format camera like the D700 is the
low light capability. Still, Micro Four Thirds is OK at 1600 and really
good at 400-800. Thus light gathering capability isn't a strength (OTOH,
after years of shooting Tri_X, it isn't necessarily a weakness either). 

Resolution is excellent for such small sized cameras. Image quality is
closer to an APS-C camera than a P&S, but camera size is closer to a P&S
than an APS-C camera. 

On top of all that there seems to be a lot of R&D surrounding the format
right now. That's resulting in good optics, good camera features, and
generally more options from which to choose.
