I found myself in the mall yesterday and wandered into a Bose store to make sure that the QC15 was still the top-of-the-line noise cancelling headphone. There's a QC20 now, but it's an in-ear thing, not over-the-ear, so even though it's five higher it's not really topper-of-the-line. Plus it costs the same amount, so it can't be better. My worry, of course, is that Bose will come out with some new model that is directly comparable to what I have but newer, and therefore better, and that this will cause my headphones to be unsatisfactory, even though they will not physically have been altered in any way by the release of a new product (unlike, perhaps, the iPhone) and they are satisfactory right now.
Perhaps this is the model of operation that Santorum had in mind?
