I seriously considered buying one, but I decided to skip it. I have an iPad 1 that meets all of my tablet needs and I'm not sure the smaller screen of the Kindle Fire would serve me well. I like the viewing space of my iPad 1.
I also own a Kindle eink reader. So I don't really need a Kindle Fire for ebooks (plus the iPad also has the Amazon Kindle app on it). I still like the Kindle Fire, I might consider getting a future version of it.
