A Kindle?

I was going through the technology section of news and came across this story:

Its about this device called a Kindle. I have heard about things like it, but never the name of the specific product. 

After reading the article, I didn't think so much about whether the device was hurting the book industry, so much as I was interested in how it compared to an actual book. We touched on the subject in class, whether people found it hard to read off screen. Being one of the people who has difficulty reading off screens, I wonder if reading off this device would be more or less the same as reading off a computer screen... If it were, I suppose the device would be of no use for me, since I print off all my online reading anyway. But I thought it was a neat little device worth sharing...
