Any opinions about the Kindle Keyboard?

I’m thinking about this for my aunt, because I am afraid the touch screen might be annoying? I have never used a kindle. She didn’t really like my iPad, because if you touch the screen by mistake it does something, plus she didn’t get the hang of tapping the screen well. But, the Kindle with the keyboard looks like it has a smaller screen, and so I wonder if she makes the font a little bigger if she will be constantly changing pages?

As I said, I have no experience with Kindles, so any info is appreciated.

Thanks.
