Whoa, Ad-Block for Metro IE
I could very well be the last horse to finish the race here but I just found out that you can use Ad Block lists in Metro IE. The tracker protection lists functionality carried over to Metro IE and you can Easy Fanboy Lists for example, as a filter and it will block out content.
Microsoft even has a few lists they suggest themselves like the truste list (cool when you want to support a site but not the BS ads they serve) or the stop google tracking list (both damn companies need to grow the hell up).
Again, if this was useful to you, I'm glad that I could help. I will say that some sites load extremely fast now. It's pretty stark the difference is and no, this doesn't block YouTube ads so you can support the people who post the fail videos you love, lol.
