My MIL has one, a first generation, we actually got it for her for Christmas two years ago. She loves it. She buys several books a month and is reading on it all the time. I have EReader installed on my cell phone and it looks like the Kindle would be a lot easier to read than the smaller screen of my cell phone.

They did just release a new version this week I think,with a larger screen. I'm going to check it out for the next holiday event for DH.
