Google Now revamps search integration in Android 4.1 Jelly Bean -- Engadget
Pro: Looks like very impressive stuff here.
Pro AND Con: Looks like google will now be able to post ads and market to the masses even better than before. Big brother (Google in this case) is watching you even closer than before.
Frankly I think it's awesome what they are doing now. Context and location aware.
