I like Google Now a lot, and get a lot of use out of it. When you've got the whole googlesphere working for you, it all interfaces pretty smoothly. Every morning I get the commute time and traffic report to my office (School when I was going to school) without having to search for it. The specials for restaurants I've rated highly pop up at appropriate times, and the newsfeed it provides is usually more on-topic for things I actually care about than reddit, certainly facebook, and several other aggregators. It integrates with the new google inbox really well, generating events for meetings and such in a timely manner. I decided a long time ago that in the world we find ourselves in, your information is going to be used, as much as you try to protect your privacy, so why not make it work for you as well as against you? I've appointed Google the steward of my digital self, and i'll continue to do so until they renege on their motto 'Don't be evil.'
