I always felt like the lockscreen itself is a total waste.
Most people don't use complex security mechanism on it but rather some slide stuff and why? It wasn't possible to disable the lockscreen for a while but at least now it's possible to disable. It never turns on by accident and i'm right in my homescreen, much better (imo)! :)
I've considered disabling mine, but I figured I may still turn it on by accident in my pocket. Risk is far reduced from say when I had a blackberry (and pocket dialed at times), but I figured it could still happen.
