A free “digest” version of F&SF is now available for the Kindle (and also for the iPhone/iPad Kindle app). I remember picking up F&SF on the newsstand occasionally when I was a kid, along with my comic books and Bazooka Joe bubble gum. They published some great stories. I haven’t picked up an issue in years though. I have plenty of SF and fantasy short stories on my Kindle, and in my Instapaper account, culled from various sources (all legal), that I haven’t read yet.
