It seemed pretty good, spent a bit of time playing with it. Lightening fast! But no extensions means no adblock, and lots of missing things like customisable search engines (I have Google, YouTube, Thottbot, Veoh, Wikipedia) as well as about 10 extensions (GreaseMonkey, DownloadThemAll, Chatzilla, WebDeveloper) as well as about 3-4 Bookmarklets.
Also, dodgy google legal things in the EULA (something to do with Google gaining rights to use anything you submit as its own legal entity? Didn't quite understand that, or why Google needs a EULA in open source software when it can just be removed), didn't like using a downloader program instead of a simple exe, dodgy Google service that isn't uninstalled when you remove Chrome (it is STILL trying to boot up in msconfig even after removal).
All we need now is for Chrome to install a rootkit and the paranoia will be complete ;p
