My eyes are suffering from reading so much on my laptop screen that I am considering purchasing a Kindle. I would use this primarily for reading, but need the capacity to take notes. I am looking at the $79 Kindle but do not like the non-QWERTY virtual keyboard layout. The other options I am considering are the Touch and the $139 Keyboard version. Since notes are important to me, is the keyboard edition worth the investment? I have my doubts about the touch keyboard's practicality, as I have an iPhone and fat finger most of my texts on that already! Is anyone using these editions of the Kindle? I have a limited budget, but if the $79 will discourage me from taking notes, it is not a wise investment.
