Funny how you do not tell us why google is the "Best Search Engine". I myself find it becoming pretty poor (especially the groups search (<...dreaming of a deja.com return...>)).

As for "fast attachment and quick sending mail", don't try google when you're in Asia. Yahoo is by far the fastest there (at least Indonesia, where I just was a day ago).

As for the google browser, I predict they take something that already exists (read: firefox) and add some completely useless features to it (that probably already exist in extensions...). Then they tie in some specific HTML rendering so they can boost gmail and other services and you have yourself yet-another-non-compliant browser (read: MSIE).
