A real change to me has been made not by the Personal Computer, but by the introduction of really good electronic book readers. When I was working in the High Tech Practice of The Boston Consulting Group (BCG) in the late 90s, I was first introduced to "electronic ink" which is a display that uses charged pigments to create a paper like, very sharp picture. At this time the company was still an early stage venture, but it developed amazing displays in the last 12 years. They can be read under strong sunlight as well as in the armchair under a lamp. And it only uses power when the pigments change direction, which is when you turn a page. I have tried a few electronic book readers, and found that the Amazon Kindle is the best. It is perfectly integrated into the Amazon store and I have two devices: one as a pocket book and the other to read larger formats. Everything in the Kindle makes life easy and emulates the way you read a book. And the best thing about the kindle is not what it does, but what it does not do: it does not distract the reader by anything "fancy".
Since about a year I sold and donated most of my paper books and re-bought them in electronic format. As I read a lot of classics, this is quite cheap to build up a decent library. Much cheaper than shipping tens of boxes of paper books around the planet, next time moving house. First I thought that I would miss the touch and feel of paper, when I read on the Kindle instead of a conventional book. But overall I found that I read much more and much faster on the Kindle. Try it and you will soon forget about the touch and feel of paper.
