I guess Apple has some level of hardware acceleration going on with Safari 4... Browser flip is running at around 60 fps, the flickr app does slow down but not as severely as the video shows. The scrolling text doesn't really work at all though hah. (13" MBP)

Are the CSS/HTML enhancements finally making it into Quirks mode in these new IE releases as well? That was one of the worst issues with IE8 and 7 for us as a company that builds widgets and scripts that need to work on every page on the web.

We're stuck without guaranteed support for position:fixed on any IE version because we can't guarantee that the underlying page uses a modern DOCTYPE.

Huh? Quirks mode is never going to change; by definition, it is to maintain backwards compatibility. If a webpage was coded back in 2000, we don't want to break those pages simply because a more modern version of the browser is available.

See: http://en.wikipedia.org/wiki/Quirks_mode#Overview

If you want to check for a browser version, there are some best practices around it. This should help: http://blogs.msdn.com/ie/archive/2009/03/12/site-compatibili...

In summary, use object detection when possible, and if that does not work for you, use something similar to:

  <!--[if lte IE 7]> 
    <link rel="stylesheet" type="text/css" src="ie.css" /> 
  <![endif]-->

Let the battle of hardware accelerated graphics begin! I don't think Google, Apple or Mozilla can ignore this as it's a major advancement for web.

I can only imagine what kind of interfaces, games and applications will be possible with hardware accelerated graphics, blazing fast JavaScript and HTML5! We are in for a fun ride :-)
