Make sure you have search history turned on in your Google account - that's when the magic happens.

Also, I'm not quite sure how the iOS experience will be compared to Android - on Android, Google Now can proactively push data to users via the ridiculously powerful notifications system, and the intents mechanism lets it hook into the other parts of the phone seamlessly. iOS' notification center is distinctly less advanced, and it obviously has no intents mechanism, so it may feel less "magical" than it does on Android, simply because it'll require more user proactivity to bridge that gap.

Here's a list of all the cards that Google Now might show you: http://support.google.com/nexus/4/answer/2839499?hl=en

Looks like it doesn't even use notifications on iOS. That's a big bummer :(

yeah, by the time I've remembered to open Google Now and slide up the cards I would very likely have realized what I might have forgotten.

For me, it's only showing the local weather, which I can see out my office window. And besides, this is CA. Forecast for the rest of the year is Sunny and warm.

I suspect that using the very simplified iOS notifications would probably get irritating quickly. Sample size of 1 but my iOS notifications tray is always a disaster compared to my Android, I think because it doesn't coalesce notifications the same way so you commonly have 5+ notifications for a single app.
