Very interesting to read this. I'm getting out of MFT because of the speed new bodies are appearing at, meaning the older bodies devalue much more quickly. I realise this happens with DSLR's too, but IMHO it's a slower process. I loved some of the MFT glass but there didn't seem to be one perfect lens for me, whereas I keep going back to the 35mm f1.8 Nikkor with my DSLR's.
My first take on MFT was "it's so small and light!", plus I loved the way the likes of the G2 handled (better controls than my D7000 IMHO) but then reality and additional lenses kicked in, and I was carrying a rucksack with 7 lenses just to go for a walk. Accepted that's probably just me, but I've decided to go down the advanced compact route instead and have a nose at some of those. So far I'm loving the X10, not quite as much love for the XZ1 but still a versatile little thing that crucially can fit in my pocket.
I way well go back to a CSC once things have levelled off a bit, never say never
