This should, in no way, be considered an official review--see CNET and CNET News for the proper shebang. I've just been using Chrome for a few hours and thought I'd dash off some quick thoughts.
First: It is fast as you-know-what. It feels super-responsive, so much so that I first thought it must be a trick. The tabs almost seem to click themselves; the autocomplete is so speedy that I thought it was reading my mind. After download and launch, it pulled in not only my bookmarks but, apparently, also my Awesome Bar history. Once I loaded it up and typed "T," Twitter.com was almost already loaded in the tab. It was slightly terrifying, actually. One note: Chrome did not import my Firefox Live Bookmarks--the RSS feeds that appear in a drop-down from the menu bar, and it sadly doesn't have this as a feature at all.
There's not even a separate search bar; you conduct everything from the URL bar. I did discover that the Ctrl-K keyboard shortcut that normally puts your cursor in the search bar in Firefox adds a little question mark to the Chrome URL bar, so the browser knows for sure that you're conducting a search. But it's not really necessary. If you type anything but a URL into the URL bar, Chrome does a search. I like it, but it takes a little getting used to.
So, that's pretty terrifying, and I guess as security features go, it's hard to miss. Hopefully it's not a false positive. In any case, like I said, I haven't done exhaustive testing on Chrome, and I haven't yet tested it with Google Docs or other Web-based Google apps. But at first blush, I like the speed, but it's certainly not ready to be my daily browser. At least not if my mom ever hopes to get an anniversary e-card.
