It's cool. It's impressive. Spooky, too.
Mark Morford explores the spooky aspect in a great column at sfgate. It's a good piece, and this is one hell of a paragraph:
Ah, Google, you great wicked benevolent super-cool vaguely disturbing Big Brother überbitch mega-company, quietly taking over the entire goddamn Net universe and most of the terrestrial world, too, one cool but simultaneously unnerving innovation at a time.
UPDATE: I later came across this, which makes the same point in a different way: Google Interiors: The Day My House Became Searchable.
