[ZombieBerry]

As QNX phones have not come out yet, that sort of answers your question. There will always be something new coming from somewhere. Use what you have for the time you need it and worry about the other units when they are released.

Battery issues with the current crop of Berries have not been settled yet, how can we answer any battery/life questions about a phone that hasn't been released?

You already have the ability to turn off apps in BBOS.
