Maybe this is old news (flag me down if it's old) but CADSOFT has a different price structure now. The EDU licenses that used to cost half of the non-EDU licenses are gone. A much nicer EDU license for free is out.
For those still in schools and teaching, take a look:
This free license used to cost $400.
Also, they're advertising with Arduino MEGA2560 design on their front page. It's pretty cool.
On the down side, they got rid of edu license on their top-tier license. Anyone wanting it will have to pay full price?
