Query: Best thing I ever got!!!

I absolutely love my Kindle! Its easy to use, has tons of free or cheap books available, takes up less room in my bag than a book and battery lasts forever, even when I forget to turn off the wireless. I did finally find a cover for it but my friend knitted me a cover and has decided to design and sell knitted Kindle covers. I haven't discovered anything that isn't perfect with it.
