As you can see on the left, page rendering still isn't quite at Mobile Safari or Opera levels, but it's a massive improvement over IE5. Inertial scrolling is solid, and the (limited) flash support is a pleasant surprise. Text wrap and zooming haven't been fully sorted out yet, so pulling out on a page often leaves paragraphs wrapped for a higher zoom level.
If these problems are addressed — and I fully expect them to be — Microsoft could have a winner on its hands. Even as is, it's a colossal step forward for Mobile IE, and one that will at minimum bring it into the same generation as its competitors. [MSDN via Slashphone]
