What Will Computers Be Like in the Future?

Today, we have desktop computer and laptop computer almost each family.
However, laptop computer is a more common in these days.
In the future, I think laptop computer will more smaller, light, and more portable.

My dream computer is like watch, it means to put on your computer your arm.
Moreover, that computer memory is more much than now.

In fact Japanese like "precise"
For example; precise mobile, precise camera, precise MP3 player...

Therefore, I hope some Japanese company could make "precise computer"

In addition, the computer program will more deverop in the future.
Now we can use any serch engines but it is only "word serch"

I really want to image or picture serch...
It means, if you don't know the words, but you know the "thing"
The picture serch can serch by a photo!
When you take a photo, that serch engine automaticly to serch the "thing" by the picture!
It is my dream serch program...
