Microsoft released windows internet explorer preview 9 to public today to help demonstrate developers the power of it. Microsoft says it is under development stages and will keep updating this preview platform every 8 weeks and will gather feedbacks from developers around the globe.
In addition to the rendering engine, the Platform Preview has a start page where Microsoft showcases five Speed Demos, five HTML5 demos, and five Graphics Demos. Naturally they all work better, or at least as well, in IE9 as in any other browser.
Microsoft is putting a huge emphasis on HTML5 with IE9, but its approach is still very strict. Since HTML5 is not complete, and likely won’t be anytime soon, the IE9 team is being very careful about which features it implements.
As you can see in the screenshot above, the IE9 team has made (some) progress in the Acid3 test. IE8 scores 20/100 on the test, and the IE9 build demonstrated at PDC scored 32/100, so given that the IE9 build from MIX10 is at 55/100, we can see Microsoft is certainly taking standards a lot more seriously.
Since GPU uses fewer watts so longer battery life can be achieved too but this can only be emphasized in low performance machines.
So when will be IE9 available as full version? Thats still not answered by Microsoft. Since IE6 was bound to release of Windows XP, IE7 was bound to release of Windows Vista and IE8 was bound to release of Windows7. Will IE9 be released with Windows8 ? Microsoft has nothing to say about this yet nor that if it will be released this year or in 2011.
