Query: An Amazing Use of Technology

I have now had my Kindle for about 4 days. At first I was a little intimidated by it, but that quickly faded as I began reading. The kindle does totally disappear, it seems no different than a book once you get used to it. It is very comfortable to hold. It has nearly cured my insomnia because I can read right up to the point where I am about to fall asleep and just put it down without worrying about losing my place or even turning it off. I love my kindle, and I couldn't be happier with it. I have no complaints at all. I must also add that just because it seems thin and sleek, it is not delicate...Don't be afraid to just go at it...This thing is solid!
