Having downloaded and installed the new version 2.x of Kies last night, my first impressions are it is a great improvement over the v1.x versions. Gone is the bloated and unnecessary array of applets. What you get now is a slimmed down set, corresponding to those on your mobile, presented in a - I'm sure deliberate - iTunes lookalike GUI. You also get a nice virtual window into your Galaxy S file system. My only quibble would be that the music app doesn't appear to organize music into Albums, Artist, etc as the app on the Galaxy S does when you sync to Windows MediaPlayer. However, perhaps with such a brief look I just haven't found the option to do this yet.
Having now sorted out my initial problems after the Galaxy S v2.2 upgrade I can say I am absolutely delighted with this mobile.
In my opinion, the new Kies 2/Galaxy S combo is looking at least as good as the Gold Standard
iTunes/iPhone combo. Thank you Samsung for listening.
