This is my first impression after 5 min of use.
1) S-Healt is integrated in the application! Great!
2) You can transfer photos from your iPhone to the clock. The installation of the app directly from the watch works now!
3) Integration with iCal works!
4) The music covers are still unseen on the clock!
5) It currently is not going the Gear App Store ... the wheel turns, turns, turns ...
EDIT: now Gear App Store work perfectly with various app...only free apps, at the moment.
