Steve Jobs kindle version

I finished Steve Jobs by Walter Isaacson of kindle version.

This is the best biography that I have ever read.

It was thought provoking and there were many precious things in it.

For instance, to focus have great power.

It took two months to read.

I looked up words in dictionary so frequently.

My kindle is installed English-Japanese dictionary. 
It is very useful.
I can know the mean of the words If I put cursor in front of them.

If I used an electric dictionary, it would have had more time to read it.

I have never think to use usual paper dictionary, it would have taken much time.

Moreover, the price of kindle version is 11.99 dollars.

If you buy the printed book in Amazon jp, It costs 4290 yen (51 dollars).

The translated version of Japanese is 3990 yen (48 dollars).

I don't know why the translated version is cheaper than original one.
