IE10 Platform Preview 1, available for download today is the first step in delivering the next wave of progress in native HTML5 support. Web sites and HTML5 run best when they run natively, on a browser optimized for the operating system on your device.
We built IE9 from the ground up for HTML5 and for Windows to deliver the most native HTML5 experience and the best Web experience on Windows. IE10 continues on IE9ís path, directly using what Windows provides and avoiding abstractions, layers, and libraries that slow down your site and your experience
Glad to see they're sticking to their guns and using MIX to announce the next generation browser.
Looks like they're moving to a long term two platform strategy, i don't think IE10 preview supports vista.. for better or worse, i guess it keeps it moving forward adapting new technologies rather than competing to support legacy. All the more reason to stick standards compliant.
Three things will ultimately make or break IE in the long term...
1.) Interoperability that isn't double-faced, e.g. open source codec support out-of-the-box for the audio and video elements.
2.) Standards compliance that is at least reasonably on-par with other browsers.
3.) A GUI that is usable, IE9 is less customizable than Safari for crying out loud!
Those are the changes that IE10 needs to be successful and I think Microsoft will have a lot of trouble with points 1 and 3. I do think their standards compliance approach is pretty solid at least by implementing more mature specifications they're less likely to have to fix stuff in IE10 that changed since implemented in IE9.
1. What does this even mean? IE9 uses whatever codeccs the user installs
2. It is, ironically more so than others who have adopted HTML5 features that aren't yet standard which could lead to interopability issues when those features do get standardized due to different implementations.
3. customizable gui for what? the point of IE9 is to be out of the way of the web. wouldn't be surprised though if a 3rd party offers some sort of skinning but i doubt that is on the radar for MS.
