Flight model is really better, the aircraft always moves a bit and you need to do micro corrections, and no more ufo movement if you do strange maneuvers.
ED should teach how to do cockpits to Microsoft, really, but at least MS gives work for the addon to tons of people, creating interest about FSx (they're smart in this).
The sound is cool, views are cool, zoom is now soft. Scenery is about the same with more objects and the same ol blurred texture like fs2004. Water is awesome! Missions are funny! Lights effects are awesome. Now let's wait october for the full version adn DX10, it will improve performance 6 to 8 times then DX9, and they'll release a free patch with tecnology upgrade.
By the way, with 3 years of separation and a lot less money (I imagine), ED still has a cool sim better than FSX in some aspects.
