If minimal/clean UI is what the IE9 team is after, they might want to consider creating a companion application.  I'm thinking a enhanced version of Links toolbar in the Windows taskbar.  Instead just being a list of bookmarks...it should provide indication when new RSS feed items have arrived and list the feed titles/links like you can in Favorites bar today.  And while they are it, make that taskbar toolbar much more touch friendly than the current Links toolbar.  That would be a toolbar I can live with.  Then again, it would be even more satisfying if this was integrated into each pinned site on the the taskbar.  I guess what I'm saying here to the IE9 team...please don't consider the UI as it stands to be fully baked...there is more that can and should be done in this release.
