I’ve thought about purchasing a kindle and made a pro/con list.
Pros:
– Better for the environment
– Easier to carry when traveling
– Keyword search

Cons:
– Not supporting my local scifi/fantasy bookstore (Mysterious Galaxy), who gives me excellent recommendations on things to read
– Difficult to share books with my husband and my brother-in-law (unless we share the kindle)
– Can’t donate them to my local library or sell them, etc.

Right now the cons are winning out and I am kindle-free. BTW, if any of you want to borrow our Robert Jordan or Tad Williams series, let me know. And if that’s your genre, I’ll also loan you Jim Butcher and Joe Abercrombie (both came highly recommended at Mysterious Galaxy). You wouldn’t kill any more trees and wouldn’t have to spend a dime.
