I'm kinda on a budget but I want to get my sister who is a bookworm something nice this year.So what do you guys think of the Nook Simple Touch?
  
  Does it have the same free e-books as the Kindle and does it have age appropriate books for HS freshmen?
  Does it have a good back light?
  Or should I just wait and save up to buy the Nook HD for her birthday next year?
