First off, I got my GM screen last week and I love it. It's really durable, easily the thickness of a hardcover book, maybe thicker. However, I noticed something that may be an errata issue. In the core book, the Data Spike matrix action is listed as a Simple Action. On the GM screen's table, the action is listed as Complex. The table is presumably taken from the book (a page is listed in the upper right corner of the table) so it's possible this is an issue in the core book and not with the screen. Since the complexity of the action didn't actually matter I didn't bother with checking to see which is correct and which is not.
I'm going to assume the tables with the GM screen are more accurate to what will be in the errata, so I'm sticking with what the GM screen says in the future.
