It is way too early to be making claims like this. Surface sales were limited to Microsoft Stores until just this week, and you could only get the RT version. Surface also includes the Pro version which uses the full power of Windows 8, and that won't go on sale until next year.
And as you regularly knock Microsoft products and don't use them, you may have missed that IE 10 Is The Fastest Browser On Windows [webmasterworld.com]. IE10 is quite a different browser on Win8. IE isn't going anywhere despite the market performance of the Surface with Windows RT.
