If someone came up with a phone that got an order of magnitude *more* of my behavioral, locational, and conversational data crunched by big services in order to leverage it all for customization/context/workflows, *that* is something I'd be interested in. Take my data. Make my life faster/better/more convenient.
I don't need someone to make secret the fact that I like show X and buy product Y and often drive to place Z. I need someone to spread the word to as many services as possible and help them to make use of this data to make my life better.
Is this sarcastic? How does all this crap make you life faster/better/more convenient? If anything, I think it has the opposite effect. We're inundated with data now to the point where the only way to truly focus on anything is to turn off the data feed. When you're "connected" you're multitasking all the time slowly accruing stress, and doing whatever you're trying to do not as well as you would if it was your singular focus.
If not sarcastic, then I'm genuinely interested in specific examples of how these help you out. The only use I've seen for any of these sorts of things is wholly marketing and revenue driven, i.e. "customer is within 1/2 mile of your restaurant, so send them a text with a 2-for-1 happy hour drink special in the hopes they stop what they're doing and go to your restaurant instead". The only application of these services where I found a benefit is with a group of friends at a large music festival where we could look at a map and see where the rest of the group was...except the cell towers were so saturated that it really didn't end up working that well.
