Like others -- I see the removal of the articulated screen as an omission for sure. Otherwise, a good tweak to the G series and a possible acquisition if you haven't owned one in quite a while. My G3 was an incredible camera -- and the shots I got from it are still among some of the best pictures I have taken.
Admittedly the RX100 is probably the better all-round camera.
I used to be a paid flickr user, but found that I wasn't getting value for my money, so I let my subscription lapse. I would happily engage again, if there were some improvements to mobile access, etc.
