Nancy, this was very helpful! Thank you so much! I actually have a Touch on my Amazon wish list; I'm drawn to the Touch because, like you, I do a lot of reading on my iPad and I'm used to the interface. I checked Amazon today and you seem to be correct that the K3 with keyboard appears to be going the way of the dodo.
The weight of the iPad is the thing that is making me think I would like a Kindle. I have massive wrists (seriously, I have the arm version of
cankles except the bulk is from overdeveloped muscles and tendons) but my arm does get tired out from holding the iPad for very long. It also gets hot, which is uncomfortable.
Thanks again for helping me confirm the soundness of my covetous impulses!
