What are the major differences between Eastern and Western Orthodox Christianities? I've looked around but can't really find a proper answer. Would anyone mind clarifying this for me?

I'm a Western Orthodox Christian, and I attended the baptism of my young cousin on Sunday, and this question just popped into my head.
Big question!  Here is my source:


  
  The culture - The East is familiar to Greek, Russian and Arabic
  languages/cultures, and the West is more familiar to Americans and
  English languages/cultures 
  The Clergy Vestments 
  The Liturgy/Mass - The
  East primarily uses the Liturgy of Saint John Chrysostom, and the West
  primarily uses the Liturgy of Saint Gregory the Great. 
  The East has an
  Iconostasis ("Icon Wall") separating the Sanctuary from the rest of
  the church, and the West either has a rail (like the old Roman
  Catholic style) or nothing at all separating the Sanctuary from the
  rest of the church
