Let them all lie down (1.7m average height) - after all this will take a while.
And then throw in 40cm between them for comfort.
You could still fit in 1.5 million people and change, or about the population of Idaho.
Each time you go to the checkout, the software can associate your phone's ID with (say) 20-30 payments happening in that vicinity.
After the second time you've been through the checkout, they will know who you are.
Costs US$199, most games are under $5. Goes with the kids in the car, in the bedroom, but still easy to confiscate and lock away.
Far better selection of educational games, not just twitch reflex shooters.
Serves double duty as a media player. Movies, music, Youtube.
Serves triple duty as an internet research / learning tool. How do volcanoes work? Look it up.
With Android 4.2 you can set up individual user accounts for each child & parent, so the whole family can use it. But it's still cheap enough that you can buy one for each person if you wanted.
Honestly, why would you get a console?
Apple: Our iDevice is now FREE but requires an iCloud account. iCloud is $39 a month.
Motorola: Hey, where's our 2.25%?
Apple's design concepts revolve around a simple experience for the 80%, and accessibility support for the 20% has historically been a long time in coming. It took 3 years for captioning to arrive on their Apple TV platform, and the iPhone didn't get accessibility features until its third iteration. I can and have recommended Apple products to others, but for this reason I am unable to use them myself.
I cannot think of a worse company to have a lock up on accessibility-related patents
The trouble is, people are lazy. If given a car like this I would just be, or pretend to be, asleep/drunk at every opportunity, letting the car do all the driving.
So you end up with a "fully autonomous" car anyway, just not a very good one.
Better to aim for perfection right from the start, Google Car style. (How very at odds with their usual ship-the-beta approach!)
What does matter: "How are we going to support journalism?" . Especially local journalism. Who will cover the zoning board. Who will ferret out corruption? The meetings of the Virginia legislature used to be covered by eight reporters, now it is covered by one.
The market always provides through emergent behaviours. I am expecting this to be the next big thing from Google. Individuals will take it on themselves to cover the zoning board and deliver reports on Google+ / Blogger. Similar to Youtube, Google will start profit-sharing with producers of quality and unique content, delivering a cut of the advertising revenue straight to their Google Wallet. Thus local journalists receive an income stream.
No matter where I go, the place is always called "here".
