And since the DX and DXG are targeted for students to read textbooks, it is strange that they didn't put the WiFi in the DXG. I realize that students reading textbooks is just one targeted group of many for the DXG, but still students would have had a lot of WiFi access at school/college. It seems like Amazon would want to encourage WiFi usage to keep their 3G costs down. But maybe I'm missing something in their logic.
