from here to there it's all about keitai. i am not so amazed. first get the interface right, make it affordable and give me a holo-display. generally i have my doubts that people are more social because of wireless. 'there is a life outside the screen' and i don't need one to discover that.

On the train, I punch in a quick e-mail message to my colleague telling her I am running a bit late. A few moments later my phone vibrates and I see a message saying that she will be later still, and she will phone me when she arrives at our rendezvous spot. I send her an e-mail message when I arrive at the appointed place, and run errands in the station building until my phone rings, announcing her arrival. We stay online until we converge in the same part of the station. I wave to her to catch her eye, and cut the line. No apologies are in order for the delay, as neither of us has wasted time. (mizuko ito)

'neither of us has wasted time'. well, i still prefer to use my time on the train in a different way.

yep, and I'd also prefer others to use their time on the train I'm on in a different way. Being surrounded by people manically sending SMS and making or answering inane calls ("the train just arrived in ..., still two stations to go") is not exactly my idea of fun.
