Hmm, that's all right.

Of course I don't need this at home or in the
laboratory, or so...

That's all no problem.


But, maybe I would like to present my project,
not at home and not at laboratory.

Then, I can't my Computer always transport.
That is the background of my idea.

I don't need this for my project at 'main function'...

But okay, then I forget this stupid idea ...
