title: What is the advantage of Gmail's client side web architecture?
body: <p>I was just wondering what is the advantage of client side architecture GMail is following.
  I mean what is the advantage of multiple iframes on the page; one with html layout and second with all the javascripts?</p>
  
  <p>Isn't it more complicated to execute all the DOM operations? (you need to search trough js ifram&lt;->top&lt;->html iframe).</p>
  
  <p>What do you experts think?</p>
