I have to say I dislike it. I had to manually kill about 10 applications which weren't really running in order to turn off location services icon. I think it fairly safe to say this will really drain the battery. If I run something which has location services on, I have to manually kill it to turn location services off. Pain in the royal ass. Also, the damn screen is making me dizzy with motion sickness.
And the calendar does suck.
There's a setting to "reduce motion" (I think) that disables the parallax background business. There's another setting to increase contrast that makes the home pages a little more legible.
