Besides the touch screen? I am a touch screen non-adopter by nature, but I have to say I enjoy using it to fire the shutter on the GF3. The camera is so small that it is really easy to touch your spot, and it focuses and fires very fast. I know the GF3 gets micro love at best, and the E-PM1 has fast become a favorite as a second body to many :43: enthusiasts, but I'm wondering if there is any compelling argument to make for the GF3 at all? Consider them to be price neutral.
