You can't always get what you want.
But the Japanese can.
Check out this list of the five advanced technologies available only in Japan: True mobile digital TV (all the regular terrestrial channels at no cost), connected cars (with a navigation system connected to a cell phone), primary wave earthquake warning systems, and home-help robots.
And my personal favorite is Osaifu keitai–mobile wallets. They put my so-called "smartphone" to shame.
Phones have smart cards embedded inside, and these cards let you add applications like electronic money, your commuter pass, an airline mileage card, or a credit card just by downloading some software.
The strength of Japan's mobile wallet system is that the industry has settled on a single smart card, Sony's Felica. Once a person's phone has this hardware, he or she can add more functionality with software.
As a frequently pocketless woman, I'm looking forward to the era of implantable chips that function as keys, wallet, and ID. But until then, I'd sure take one of these phones.
