Added another search macro --- the search scope covering Microsoft Surface technology.... Will certainly keep this one updated!

Browse to http://search.live.com/macros/t/sf or add " macro:t.sf" in your live.com query.

Btw., you can view the list of all those search macros at http://gallery.live.com/Author.aspx?a=d488a303-0a92-49d9-aac3-be314bb8ee17
