My guess is you're forgetting, and Glenn can confirm ... Google remembers every search / lookup done. Combine their knowledge of your MAC address and your IP (from the searches), and you now become a potential victim for targeted advertising. You always have been, but now they know where you were, so the local plumbing store's ads now come up.<br>

<br>Google (the search engine) has no knowledge of your MAC address. It is not transmitted over all the hops between my ISP's first point through the internet all the way to Google. Only your IP address makes it that far, and yes they do log it, but not the MAC address.<br>
<br>The Google van doing Street View only visits a certain location every so often (at most once a year in our area, if not more)? The correlation between IP address and MAC address (if they did that even), is a snapshot in time. Most ISPs will NOT keep your address the same for that long. So this data is very transient in nature, not to be useful in correlating WHO, just a database of devices for geolocation.<br>
<br>At best, if they had that data (IP vs. MAC) is that they can use it for things like: how much market share does each ISP has in this part of the city, but not much more than that.<br><br>Compare that to things like phone number, which is a) permanent for a land line for decades and b) referenced against one or two people in a public database (phone book), and it has far more implication than the transient nature of you IP address (DHCP leases expire after a few months at best) or MAC address (routers get changed in a couple of years). <br>
<br>Combine that with phone companies (and magazines, ...etc.) selling your REAL name, address, ...etc. to marketers, spammers, and scammers, and you see which threat is worse. One we have accepted as part of life for decades, and the other of a much lesser degree and we are making a bigger fuss about.<br>
