I just got my second digital camera, after having sold my Fuji Finepix 3800 a couple months ago, I got my G6 yesterday. I am very impressed! I'm nowhere near having figured out all the features/options on the camera, but the little bit I played around with it impressed me. Picture quality is fantastic, focusing is relatively quick and all the options are nice to have. I'm also very impressed with the build quality of the camera, feels very solid and well made.
I was going to wait for the next G camera, knowing that DIGIC II would bring much faster focusing and USB 2 support, but I'm glad I didn't wait. I bought a 512 MB CF card and a USB 2 multi-card reader for my PC, so the slow transfer issue is taken care of.
