Too bad it isn't available for Macs yet:
A recent contest at CanSecWest, an event that brings together some of the most skilled experts in the security community, has demonstrated that the three most popular browser are susceptible to security bugs despite the vigilance and engineering prowess of their creators. Firefox, Safari, and Internet Explorer were all exploited during the Pwn2Own competition that took place at the conference. Google's Chrome browser, however, was the only one left standing—a victory that security researchers attribute to its innovative sandbox feature.
The contest awards security researchers with hardware and cash prizes for finding efficient ways to trick browsers into executing arbitrary code. During the first day of the competition, the contestants are required to do this in default browser installations without plugins such as Flash or Java, which are commonly used as vectors for attacks. Researchers typically prepare for the event far in advance by finding zero-day exploits ahead of time.
