From what little I have seen or used Google now, it's pretty awesome. I today searched for a company nearby using safari and Google search on my mac. Not long after, directions to said company showed up on Google now.
Set an appointment etc in s-planner with an address and it does the same and tells you what time you need to leave to get there for the appointment time.
Any time I leave home it tells me how far I am away from home. I'm sure it does more and I'm just scratching the surface
