Love the way it asks for information Google already knows :P
Not only does Google know my email address, it's displayed in the top right corner of the page!
Location could be taken from many places, most of which admittedly they probably couldn't use due to privacy, but most browsers support Geolocation.
It's nice that they are asking for the information even though they don't need to.
