These heuristics sound good. Does "dominant" mean >50%?

As you say, the difference to a user will be obscure, any toolbar button will 
just become "that button which makes YouTube a bit better but breaks 
scrolling". I'm also worried about the prompt when there are embedded plugins: 
there's a lot of useless Flash around the web which'd trigger it for a lot of 
pages.

Perhaps any exposure of it in the UI could be avoided with additional 
heuristics:

  c) Enter native mode when there are embedded plugins larger than
     300x200 (or some %ge) in the viewport and the user hasn't
     interacted with the browser (rather than the plugin) in
     5 seconds.
  d) Enter native mode when a plugin gets focused/clicked on
     and go back to tiled mode when the container gets it
     back.

Comments welcome :)

Cheers,

Andrew
