General reaction so far after a few days:
Good:
- Its much faster than PIE. Ive even stripped out all of the useless crap i don't use and it feels like a new phone.
- New navigation is cool but you cant use it with the home button if you have a 3rd party launcher as your default. It simply get's disabled - Not cool Samsung.
Meh
- UI improvements are subtle at best. There isn't that much changed but it's a very good start performance wise.
- You can still use the new navigation but only via switch task's. Swiping quickly left/right does the same thing ( In fact i prefer this )
Bad
- Spotify is broken... dunno why (even the beta's don't work).
- Theme Park also crashes when saving a theme
- Everytime i pull down the task bar - i see a msg 'Cant find target package' - wtf.
Im looking forward to some custom rom's on the official releases
