The multiprocess approach to browsing is interesting, it was really the only thing that interested me in Chrome. I have only used it for a couple hours but haven't managed to crash a tab to see if it really works the way they said it would. But I have run into a couple of bugs, one is that it can get really weird when your typing text into a text box, for some reason it doesn't display it properly and will overwrite text when in reality its still there.

On the security side of things, I noticed they have a save user/passwords feature but its completely open and cannot be locked by a master password. So even if your browser is closed, anyone can open it up and just click "show password" and look at any of the saved passwords you have in plain text. At least in FF3 you have the option to lock it with a "master" password.

Also, I've had some trouble with it on some ssl logins where it doesn't send the password correctly.
