I've been really happy with its bundling of information. Taking a trip soon. Booked a flight for me, a flight for my girlfriend, a car, hotels on various nights across the vacation period, etc.
Google grabbed all the info and bundled it, put it onto my calendar, and into my email in a specific place. Saved a bunch of trouble, now I have reminders on my calendar of when I check in, where, when and where my flights are, etc. And it will tell me when its time to leave for the airport, though I find this last thing a bit buggy as it will tell me when to leave as if I wanted to arrive at the airport at the time my flight leaves, and not an hour before (minimum).
I'm really enjoying what Google is doing to make my life easier.
Previously, I would have manually moved each email into a trip folder then spend time adding each item to my calendar along with confirmation codes, etc. That takes a while.
