Search Field Default Dumbness

Ok, lots of sites used to use default text in search fields (and other form fields) to describe what you might put in there. Some still do, including eBay, but they usually have the sense not to act on the text if you actually click the submit button. This one doesn't seem to have worked out that PRODUCT SEARCH is just the text that was already in the field. It seems less and less common to use the default text in this way, and a bad idea unless space is a real premium and there's a good reason to have to tell users what's expected of them (clue: a standard product search field isn't a really good reason).
