My disappointments after this update:
1. Still no Voice Mail Notification.
2. No Calendar notification
3. No MMS
4. Cannot click/swipe on notification icons on lock screen
5. No solution to avoid scrolling to top on long list/pages to access pull down menu.

I like after the update:
1. Butter smooth - no lagging so far
2. Bluetooth audio A2DP lockup seems to have resolved with my car
3. Lipstick does not seem to take over the system. Haven't had to kill it.
4. Haven't had to reboot since the update
5. Contact showing type of phone number

Final thought.
I still like the N9/Harmattan interface. Why did they have to change it? It is like they changed it just to be different. It was so natural. We just needed some fixes. I wish someone starts an open source project to put Harmattan like interface on Nemo.
