After 8 days of using Chrome (where has the time gone?!?), I'm really liking it.
It so fast

that I have effectively retired Firefox -- even with all the add-ins that Firefox has and I thought I couldn't live without! Chrome is so fast that I can even put up with the ads.
A couple of days ago, Chrome was updated and the Internet Explorer capability is MUCH improved. So I am not using IE for those few websites that Firefox cannot handle any more.
Only website that I'm seeing issues on, and I've reported to Google through their easy site reporting mechanism, is Adobe.com. Not sure if that's because Adobe is using Flash, Flex or some other product/technology to build their pages.
Hope that you Mac guys get to try this browser soon. I know that Safari is OK on Mac but it is as slow as molasses on Windows. Maybe Chrome will translate well to the Mac too
