+1 to PaulMdx. Not running=no problems, but when App World is open the device virtually comes to a complete stop. I often times can't even exit out of App World. I hit the escape button and walk away for 10 minutes and MAYBE when I return it has exited. Forget trying to exit using the close command via the BB button. I usually end up having to do a battery pull soon after accessing the store. It isn't worth it at all.
