The keyboard I bought in Rakuten was delivered today.
It is wireless, so it use bluetooth.

I always use a mac computer(Macbook pro).
Sometimes, I use a windows computer(vaio).

But, my windows computer have a little screen.
While it is very convenience, I have to concentrate on the screen.
It makes me tired. So I often use this computer through another wide display.

Now, I use my windows note computer as a desktop computer.
In addition, this keyboard may make an environment clean.

That's all. Thank you.
