yes... the google logo is on everything (except the mouse charger).
Are you an AdWords advertiser? If so, any indication of whether you're getting this for publishing or advertising?
yes, i also do some adwords advertising for a couple of my sites. the address on the box seems to exactly match my adsense address - my adwords address was entered a little differently (st vs. street etc)... so my best guess is that it is for adsense.
