Google CEO Eric Schmidt says Chrome for Mac is coming in a couple months, but if you're impatient and only mildly adventurous, you can run it a surprisingly solid early version right now.
Google warns that Chromium (essentially, the open-source part of Chrome, which is what you'll be downloading if you take the plunge) "still lacks certain privacy features, and is not appropriate for general consumer use". Fair enough, but if you're just dicking around and want to get a feel for the interface and speed (we like), it's good enough now you can stream videos and browse without crashies (though you might see some weird drawing errors when there's Flash involved). Just don't cry if you run into any bugs, 'cause we're not even talking beta here. [Direct Download (DMG file), Chromium]
