"worth it for the G-Nex"5.0 starson by thatguy8729
Pros: More responsive, better graphics, and I love the improvements to the notifications.
Cons: The adjustments to the keyboard take some getting used to. I haven't really used it enough to have found any major problems.
Summary: It's a lot like the 2.2 to 2.3 update, not a "major" update like 2.3 to 4.0, but if your used to 4.0 you WILL see the difference.
