Prof .. I understand your point about everything being breakable. But from the feel of it, it felt like if the Nook/Sony sort of lightly hit something (edge of the bed/table) its gonna survive. Kindle probably would but it just didn't feel like it.
I don't really need a month of charge. I would be pretty happy with a week or over

. I would also use almost zero wifi and minimal lcd usage I think. I find the buttons more comfortable from what little I gathered using Nook. I do often have multiple books open, specially if parts of them are going slow for me. Otherwise I have the bad habit of trying to finish a book in a sitting. Which is not good for other things .. I know but
