When I am on the road, i still need my entertainment. Usually that means reading. I carry my kindle 3 with me, the simplest version which during last Christmas was selling for 45$ online. I pirate books, lots of books, mostly old ones, sometimes new ones, but always lots of good books. With my kindles amazing battery life and portability, I read about 5 books a month, before the kindle I read about .2 books a month. I think in the last 8 months since I got my kindle I have read more then i read in The 27 years before that.
Great books: Stranger in a strange land or any classic Scfi, any of Kurt Vonnegut’s books, Nickel and Dimed, Into the wild, brave new world, 1984 and many many other books which you can very easily pirate 🙂
Music! If you want an MP3 player get one, I don’t carry one but they can be fun, especially to introduce foreign people to your favourite music, which they have never heard. A great traveling song – wonderlust king by Gogol bordello
