Microsofts Marketing for IE9 and the truth

Have you checked the IE9 RC?

M$ states 99% compliance to HTML5 and 100% compliance to CSS3.
See Microsoft IE9 Blog


But this is the truth:

• Worst compatibility points on http://html5test.com
• NO text shadows
• NO border-image
• NO transitions
• NO gradients
• NO multiple-columns
• ..and so on.

Conclusion: You must test the html5/CSS3 features of IE9 yourself. Never trust marketing bullshit.
