Kindle

I've decided to do my individual topic for 644 on Kindle readers and other technology like it. I want to specifically look at the issues this technology raises for libraries. Some of my initial questions are:

• What are the basic functions of Kindles? What can they do? What can't they do? Pros/Cons?
  
• What is the cost of owning a Kindle? How accessible is it to the average consumer? Are there extra costs involved? Are there other options for wireless reader hardware?
  
• Who is using them at this point? Are there projections about who will be using them in the future?
  
• How is the public reacting to this new technology? Writers? Readers? Librarians?
  
• How will wireless reader technology impact library use? (Especially due to the fact that there are many options for free downloads of books from anywhere Kindles get wireless)
• Is there a way in which libraries could use Kindles, or appeal to Kindle users?

I've started my initial search and I'm already amazed at the technology, and slightly concerned as to how this will affect my chosen profession...:)
