A side by side comparison with lots and lots of Internet Explorer 10 Mobile improvements.
With the upcoming Windows 8 release that features IE 10, we take a look at the web standards support (HTML5) and compare it against both Windows Phone 8 and Windows Phone 7.5.
Sure, we could just talk about the numbers: 300 vs. 138 but there is a better way.
And if you are not into the graphs, here is a text only version.
