ITreviewed posted a review on Microsoft Internet Explorer 8 Release Candidate 1

IE8 delivers significant security improvements over its predecessors and is more robust and faster than IE8 beta 2. But given the extent to which cybercrime relies on social engineering, users of IE8, like other modern browsers, would be well advised to remain cautious in the sites that they visit and the information that they disclose online. It's only a matter of time before someone figures out a way around IE8's new defences. The new version brings enhancements in private browsing, accessibility, overall reliability and speed. RC1 reaches a significant development milestone towards a browser that can compete on closer footing with Firefox, Safari, Chrome and Opera in terms of features. However, Web standards support (especially CSS 3) and performance is still far behind the competition. Maybe it's time for Microsoft to give up and let Internet Explorer make way for the generation of browsers.
