Nook vs Kindle

I have both the Nook and the Kindle.  I like the Kindle better.  Why?  Several reasons, it is smaller.  I have it in my purse all the time and can pull it out any time.  It is light and doesn't weigh down my purse a lot.  Finally, library books do not expire from it the way they do off of the Nook.  Yes, you heard me correctly.  The Nook has a 'time bomb' that makes the book expire at the end of the 2 week library loan period.  With the Kindle, if you do not turn on your wireless, the book stays on your Kindle and is available to read indefinitely.  Shhhhh!  Don't tell.
