I really enjoy the new S60v5 version with notifications. Overall the software and service have been reliable and enjoyable. I miss the scrolling "wall" of images from the S60v3 version, and find the touch based navigation to be a bit failure prone (swipe more then 50% of the screen, it scrolls by 2 images instead of one. not possible to scroll by more than 2 pictures).
Overall this is a great first release. There is plenty more to do, but considering that this version also brought more than just a vanilla port of the old version to S60v5 it is still refreshing and great to have.
