That reminded me of Anchor Man, 'I'm kind of a big deal, I get a lot of notifications' lol
Just kidding mate, seriously I think if people need a spare battery then fine.
I think its just nice to have just incase, alot of people usage are totally different and depend on what you are doing that day. My problem is I get my notifications from twitter where I follow like 10 people so it can get out of control sometimes.
