One of the main improvements I've noticed is the battery life. It's definitely better than it was before the update. I've been browsing the net now for 2hrs solid and the battery has only gone down by 6%. Interestingly, there are a lot of articles on the net about how battery's are draining quicker since the update. Not so on my iPad! Also like the new predictive feature on the keyboard. Not sure what the time lapse video feature is about. Another little feature I like is the ability to change font size, I like a small font.
