Here is my feedback concerning the touch screen (also came from Garmin):
Pros:
there is a lovely ‘minimal’ mode for a wake up gesture. It is just great, love it!
entire dynamics in switching between wigdets and scrolling works just perfect for me.
Navigation/maps in sports mode is implemented incredibly good. It works way better and more responsive than in Garmin.
Cons:
as pointed above - no tap-to-wake option. I really hope this will be updated soon!
also compilations are not equally responsive on all watch faces - I suppose this can also be fixed in next updates.
