Great, fantastic, brilliant - well done.
The only thing that's got me scratching my head is that they have gone back to calling it a 'beta'. It must have been difficult to remove the beta tag in the first place but to put it back on makes the polished giant look a bit edgy.
Don't get me wrong, the beta tag is justified and there are some decent improvements but I always find beta is used to say 'this might be a bit crap'.
I'm sure that's not the case for Chrome because Google rarely get it wrong... right?
