Google Now gets you just the right information at just the right time. It tells you today’s weather before you start your day, how much traffic to expect before you leave for work, when the next train will arrive as you’re standing on the platform, or your favorite team's score while they’re playing. And the best part? All of this happens automatically. Cards appear throughout the day at the moment you need them. So far so good, but...... sending the hole time personal data?! Whats going on there? My first impression was...."wha ta fu**? - Its just a fu**ing weather app!" Google wants to analyse everything!!! So, my opinion on it - even back a market research tool - not a useful aid, at least not as useful as Google thinks!
