Sainsburys still had nooks on display for £30. Stock might be another issue, mind.
I've started reading again since I bought mine.
I've been downloading more books than I've been reading since I got mine!
A couple of useful (free download) links:
Project Gutenberg: Free ebooks - Project Gutenberg (The biggest and best)
Arthur's Bookshelf: Arthur's Bookshelf (Laid out nicely, even though some links don't work)
I've also installed Calibre on my PC at home, which can convert between ebook types!
