Here are some of the latest statistics from the W3C that should be taken into consideration when designing and building your next site.
Firefox continues it’s steady rise in popularity as IE6 slowly declines. Look for IE7 usage to continue to rise as more new computers are shipped with it pre-installed with Vista.
Browser Usage:
IE6 37.3%
Firefox 34.0%
IE7 19.7%
IE5 1.5%
Screen Resolution:
80% of viewers are using a screen size with 1024×768 resolution or higher. Good news for those who have been waiting patiently to break out of the constraints of skinny 800×600 layouts.
