Recently, I am looking for a used smart-phone that has no voice communication function(No SIM card).

I don't have an intention of "I want to put smart-phone into place", but begin to think "I will get into trouble if I remain undone it".

For younger, the speed of Japanese input method of smart-phone becomes really redoubtable.

This speed might be rather faster than that of input for my PC.

In addition, the population of smart-phone users is overwhelming now.

When I become older and oral communications becomes more difficult, I think that a smart-phone might be a last method.

This thought might come to me because I commit both care and nurture.

-----

My hypothesis is "smart-phone becomes substitute for a board of the 50-characters".

Contrary, people might deal with people who cannot use a interface of smart-phone

Have I taken care of people who could not use push-phone service, FAX, PC, e-mail, and web-browser, and shown alternative methods, for example analog, printing and other services ?

I am afraid that I have not done.

If someone points out that I left some people who cannot use e-mail our of communication, it cannot be helped that I say "YES".

However, I don't think that it is "severe".

Perhaps abandoning those who can not take it into daily life even when "paper", "pencil" or "telephone" has appeared, I believe that civilization has developed.

The development of technology and the paradigm shift of civilization always flows to "easy", however, it is unavoidable that a certain amount of "hardship" should be needed in order to reach that "easy".

"Youth" cannot feel as "hardship" against the power and speed, and I used to be on that side once.

-----

Anyway, life is designed in order to match each other.

Those who have abandoned are abandoned.

Still, even though it is inevitable to be abandoned, I think we can choose the extent of being abandoned.

Therefore, at the beginning, I have to go back to "Japanese input of smart-phone".
