Query: Works great. Love the download feature

I really like the overall functionality of the Kindle. The screen is very easy to read and the battery life is LONG. I think the case design is a bit weak though. Its really easy to hit "back", "next" and "previous" buttons unintentionally and the case has a lot of sharp angles that are not all that great for grasping for long hours. Love the dictionary function. Before Kindle, I didn't care enough about words I didn't use/know to pull out a dictionary, etc, but with the easy lookup feature, I always look up words I haven't seen. Overall I'm happy with the purchase, but I look forward to version II (whenever that might be). Maybe Amazon will offer a discount for version I buyers :)
