I've been an Android user for a while now, and there are reasons beyond what I've outlined before for why I keep up with the latest software. The actual usefulness of it.
But living in Canada, that can be an issue. Case in point: Google Now.
Google Now, if you don't know, is a smart tool that's included with version 4.1 of Android. It's too easily called a competitor to Apple's Siri--because of the many things you can do with it, you can try to ask it questions.
Apologies to you Pats fans.
But the main functionality, when you swipe up from your home button, is a dashboard of information. It's designed, as they say, to "get you the right information at the right time." Most of it is location-based--it can figure out where you work and where you live, giving you transit or driving directions to and fro. It can give you the temperature of where you are.
But I rarely ever use it in Toronto because the transit directions can hardly be trusted (for that, I use a fantastic app called Transit Now Toronto for TTC) and the temperature is something I keep as a widget, so I don't need to go into Google Now.
That's possibly the first hurdle of its usefulness, that you have to swipe up to see this information. I've heard some say that Google's next logical step would be to give you the option of making this your "home screen." I can see it being glanceable information at that point--like Microsoft touts with Windows Phone. You would, ideally, unlock your phone to a Google Now dashboard or have it in the lock screen itself (though some information is personal, as you'll see).
When Google Now was first available to me, I found one great use for it. I would Google a store or restaurant and Google Now would scrape my search history, realize that I want to travel there, and offer to navigate to it. Super useful.
Then I went on vacation and a whole new world opened up to me. Before my flight, I had questions anyone has: Is my flight on time? What's traffic like? What temperature is it there? I was going to Google all of that, but something pushed me to check Google Now. Here's what I saw:

Fancy that! I guess I shouldn't have been surprised. My emails about my flights were in my main Gmail account, so it has the information. But here it was, displayed in such a simple way, giving me a flight number, terminal, time and, the real great part, the ability to navigate to it (in transit time, because that's what I set up as my preferred method of travel).
I scroll a little further, and I see this:

I had completely forgotten that I ordered a couple of cables. But there it was, with the option to track it on the USPS website (directly, I didn't have to enter another number when I got to the site). Not what I needed to know before my flight, but good to know the cables would be there when I landed.
Scroll a little further and I see this:

Both cards, not just one. Where I was going and the dismal cold I was leaving. (I included the second card next to it because at the time I checked, there was a wonderful plus/minus coincidence)
Now I saw the value of Google Now--but I saw it only when a specific situation presented itself. I'm not always shipping things, I'm not always flying somewhere. Sidebar: I can now see why tech journalists glow about this feature because they generally are travelling and shipping. In Toronto, normal use of this feature is limp.
When I got to Tampa, the features were much more fleshed out. It would offer cards with movies based on searches for actors that you've done, nearby attractions in the city with ratings and reviews, the exchange rate, nearby food joints...all things that I totally could use in Toronto, not only on vacation.
But that's the issue with Canada being a second-class citizen in the world of consumer technology. I see the value of Google Now, and the potential for it to be a truly intelligent part of a mobile phone experience. It's just not perfect. Apple skirts this by forcing you to ask Siri something, but I love what Google is attempting in trying to predict what you need.
Which is what a good assistant does.
