I call the future is: Your world in your phone sized device backed by the cloud, with the option to use anonymous, mindless larger displays when in close proximity. I've seen the future, and that's not it. :-) Too expensive, and just can't be ubiquitous. How many large displays can you put in a bus or in the stands of a football game or at McDonalds? With that said, such devices will exist, but they'll be your TVs in the house. And on battery life. Even today people can get some decent efficiencies, and it will get better. Here's what Engadget had to say about the Kyocera Echo (a dual screen phone, with a 1370mAh battery, which is smaller than the iPhone 4s): "We took a different approach. We charged the phone fully and then went about using it as we normally would for an entire day -- checking emails, browsing through TweetDeck, zoning out on a conference call for an hour or so, watching a bit of Sprint TV and playing entirely too much full-screen Pac-Man. We'd say 70 percent of our usage had both panels open, which is likely far greater than what you'd see after the novelty wears off. That said, we managed around 15 hours of use before it petered out, and on a second try -- one that involved far less dual-screen action -- we squeezed out 22 total hours. " 15 hours isn't ideal, but with some work that we're seeing out of Samsung, I don't think 24 hours is out of the question in a year or two at all. And that's with a relatively small battery. EDIT: You have to love cowards that downvote, but don't dare say a peep.
