I agree, and think it is more specific and accurate than just saying
"device". I was hoping to clarify in my last email only that this means
a _particular_ user agent; I really think it's clear enough from
context, though, reading it again.

>> Shane and Kevin -- The phrase "user agent" in the text is intended to refer to a particular user agent (not "Chrome 26" but rather "the browser running on Dan's laptop". I hoped that would be clear from context, but if it's not we can clarify. I may not be able to identify your device per se, but can identify that this is the same browser as I saw before. I think this is the case with using cookies, for example. It seems more accurate to me than lumping it all under "device", and appropriate since the text of our document is elsewhere focused on user agents, unlike the FTC text.
