I think that this is both a smart move on the part of Amazon, and also a portent of bad things to come in general. One of the ideas behind the tablet 'ecosystem' in general (at least the one spawned by Apple), is to control the vision and view of your computing experience. Given that standard 'workstation' type computers are historically more free-form in how they allow you to access them and work with them compared to tablets, I suppose forcing ads upon the users was the next logical step for the structured tablet platforms. I wonder more generally if this is the first shot across the bow and it's something we will see from Apple and Google in the future. I think the question at that point is also... how soon until the new Kindle gets rooted and these ads blocked ;).
