I sold my G1 a few months ago after buying an E-P1. I didn't really want to sell it but I had a Leica M9 to pay for so it had to go.
But, boy, have I missed that brilliant EVF and the articulated LCD. So, I've just bought another one on eBay. And I paid £110 less than the selling price of my first G1.
I'll be keeping the E-P1 though. With the pancake lens it is perfect for those occasions when even the G1 is too big. Or when I want to shoot a little video.
