Hi Vicki and welcome to MR.
I've got the daily edition and love it!! I don't have a kindle so I can't really compare the two, the link Geoff gave you will help, and there is also a nice
comparison matrix here as well. I got the Sony for the touch screen and the fact that it let me read more types of books from a greater number of sources. I don't have any complaints except that the Sony library software is not really good but there are nice alternatives to it like Calibre.
If you have and specific questions feel to ask, there is also the Sony specific forum as well.
What do you mean "horrible Ohio weather", do you get that down in sunny Columbus? Columbus is where us people from Cleveland go for vacation
