If you have read some of my previous posts, I am a big fan of the idea and potential of e-books. My experience has shown that reality does not yet jive with the idea. E-books are simply not easy to use or read (unless you have a Kindle/Sony e-book reader). The DRM that I have encountered destroys the entire experience (not being able to print is ridiculous).
The venerable David Pogue of the NYTimes has written extensively on the subject. He is doing a test. Read about it here. David, I hope it works out for you. It is a noble and brave test but as a lover of the future, I am glad to seeing you taking the ultimate plunge. Much luck.
When the Kindle 2 comes out, I hope someone might buy me one (*hint hint*).
