Is it safe to use the HTML5 button element for production websites?

Is it still worth using the traditional input element for buttons or can I start to use the HTML5 button right away?

I have been able to verify that the button element works on the following, but are there any issues that I need开发者_高级运维 to be aware of?

• IE9 (3 modes from F12 tools)
  • IE9 with IE9 standards
  • IE8 with IE8 standards
  • IE7 with IE7 standards
• Chrome 13
• Firefox 4
• Safari 5

Note: I am not supporting IE6-, I am interested in IE7+, Chrome, Safari, FireFox, Opera, etc.

I say use the button element as you then also get free accessibility via the keyboard with it, which can be handy.

Plus if it's a button, use the element that's made for it!
