I think your second point about a Version 2.0 is very likely. I ended up getting the 1.0 anyhow, because most of the changes seem to be software related (meaning that 1.0 can get to 2.0), except for 3G. And, I wouldn't use the 3G anyhow, since I'm not interested in paying a heavy monthly fee (and most here already have smartphones to do those things anyway).
As for student/prof reviews, there are a couple on http://groups.google.com/group/entourage-edge-fan-forum
. One is from Lisa, a professor and the other is from Cheyenne, a student. There's also an audio interview with a prof on enTourage's community page. The interview is rather rambling, but you can glean several points about the eDGe if you do listen to it.
