Internet Explorer falls below 50% market share
Woobius traffic specs (quite representative of the enterprise space, so more realistic if you're doing an SaaS that also targets enterprise users/customers), are not too far off, but not 50% yet.<p>IE: 56%
Chrome: 20%
Firefox: 16%
Safari: 5%<p>IE versions are broken up as:
IE6: 10%   (= 5.6% absolute)
IE7: 25%   (= 14% absolute)
IE8: 65%   (= 36% absolute)<p>In other words, dropping IE6 support is not yet plausible. But we've already opted to provide only functional support for IE6 - i.e., things need to work in IE6, and not look totally broken, but they don't have to look great.
