Personally I now prefer reading from my Ebook Reader. I just find it more comfortable to hold.
In general, if I have a book that isn't available in digital format, I have created my own. Most recently I bought a couple of Jeff Noon books (both of which I had previously owned and then thrown away during a clean out my wife made me have). So far I have only gotten round to scanning one of them in, but I now have it in digital format
