I just got the $139.00 Kindle and I love it. It's the Wi-Fi one. I just need to be near a Wi-Fi to download, but I can read on it anywhere. I have At&T UVerse for TV and Internet and AT&T helped me set my Kindle up to use the same Wi-Fi as my Uverse. I download books at home. I've read until 3 a.m. and had no eye strain problems. Also, Consumer Reports rated the Kindle as the best overall. I had no problem adjusting from a book. I like that I can use either hand to turn pages. I belong to a book discussion group 5 out of 7 of us have a Kindle and all of us like them.
