This one surpasses IE10 --The new IE11 -- Whether Ms releases this before W8 blue is "officially" released I don't know.
One feature that sounds good -- is the fact that you can stop browsing a site on one PC and then immediately on another PC / device such as a phone / tablet continue where you left off. -- I can't test this yet as I don't have TWO spare machines to try W8 Blue on yet. It WILL have the syncing ability across all your devices as well. Hopefully IE11 will make its way into the current W8 release.
