According to Amazon.com the Kindle version will be available on February 24th but you can pre-order it here.
Here is a description of the plot:
Following a nasty break-up, lovelorn college English instructor Wesley Smith can't seem to get his ex-girlfriend's parting shot out of his head: "Why can't you just read off the computer like the rest of us?" Egged on by her question and piqued by a student's suggestion, Wesley places an order for a Kindle. The device that arrives in a box stamped with the smile logo--via one-day delivery that he hadn't requested--unlocks a literary world that even the most avid of book lovers could never imagine. But once the door is open, there are those things that one hopes we'll never read or live through. Get it only on Kindle.
