Yeah, I have a GF1. In fact, hilariously, it's Alex Rainert's old one with Panny 20mm pancake which he was selling on ebay. That camera has been absolutely awesome, and about 2 days after I bought it was used to take the picture of my youngest daughter coming into the World.

m43 cameras in general are a good compromise on image quality and size. GX1's and GF1's in particular are not especially expensive used.
