I don't totally get this. Google put a Now search bar on the Android home screen. I type in "ice cream" and it not only reminds me of several "ice cream" searches I've done recently on the desktop browser, but brings up all sorts of hits for local ice cream including a map, reviews, Wikipedia, etc.
It's not clear what more value or convenience someone can add to this. But, I guess the investors know something I don't.
It's been awhile and no clear sign they are sending out the invites yet...
