According to Computerworld, the release of the Mac and Linux betas for the software helped push it into third place, past Apple's Safari browser. The week of December 6-12 saw Chrome hitting 4.4% market share, an increase of 0.4%, beating out Safari, which held 4.37%; to show how important the browser hitting beta on Mac OS X was, before the release, Chrome held 0.32% of the share on the OS during November, which shot up to 1.3% afterwards. It was said that the split between people switching to Chrome was evenly divided between Safari and Firefox.
Well -- it's definitely faster than IE8 and Firefox.
