This is, quite possibly, the best screen yet released for D&D, regardless of setting. Including tables for everything from Cleric's turning checks to Influencing NPC attitudes, as well as a handy Days of the Week and Months of the Year guide for Eberron's calendar (among a large number of other goodies), it's clearly meant for a high-roleplay campaign. Things like Item Breac DC's and what actions provoke what are also included, and it does quite a bit to lower the ammount of time some of the more rules-driven areas of the game take up in game time. Also, since it uses the D&D Deluxe Screen landscape format, I really don't feel half as "cut-off" from the players as when using my Forgotten Realms screen.
Still, there are areas in which the screen could be improved. There are three emblems (the same as the O in the Eberron logo) on the DM's side of it in which another table could be placed. Also, when viewed from a high angle the text doesn't contrast very well with the table background... and since my group generally plays around a coffee table, my players can easilly tell when I'm looking something up when I have to lower my eyes almost to the level of the screen. It's something to look over before the game while players are building characters (or before they arrive) or during the occasional in-session break, but otherwise to be reserved for really sticky deal-with-the-rules-lawyer situations.
