I was just reading about the new Kindle Fire and its $199 price point, which is pretty amazing.

It's not an iPad killer in terms of all the bells and whistles but at $199, you can by two for the price one of the cheapest iPads ($499) and still have money left over. I don't know if this will have an impact on the iPad but, at this price, I think it will have an impact on iTouch sales as well as other non iPad tablets.
Kudos to Amazon for what looks to be a solid product launch strategy!
