Can't wait until a Mac version of Google's Chrome is out? There is now an alternative to running it inside a virtual machine: CrossOver Chromium. It runs on Mac and Linux, and is essentially the open source version of Chrome (chromium) wrapped in Wine (Wine is No Emulator) that mimics Windows as much as possible. CrossOver Chromium
Update: I installed it, ran it, threw it out. It interesting to see that it runs on a Mac, but it's dog slow doesn't blend in well with the rest of the desktop and crashed as soon as I went to Amazon.com.
