Sold the G1 but....
I hung on to the M mount adapter. I still have hopes that Olympus will produce the little compact m4/3 camera sooner or later and when that day comes then I will give a second look at micro 4/3.
Frankly I am more hoping that Canon or Nikon will jump on the wagon instead, I would much rather buy a Canon EVIL camera then an Olympus.
In the end I did like the G1 for being a compact high image quality machine but I still thought it was too large for what I really wanted which was a replacement for my Ricoh GRD which after today looking at different compacts like the Panasonic LX3, Canon G10 (not compact!) and Nikon P6000 thing...that there is no replacement for a GRD in my book. So I will wait and see what the horizon have in store for us. A Sigma DP2? m4/3 compact Olympus? Who knows.
