DR Jane, I know nothing about B&N's pricing on their Nook.
I know that I can get Borders' Kobo, while we have them, for a discounted price.
IF I got one, I'd be getting it primarily for Mum, who could read books on it as if they were large print editions.
Plus our store would get major credit if our employees purchased a Kobo - there's some sort of nonsensical corporate contest involved. . .
