Just to let you all know, EAGLE 5 has been released.
It's more user friendly, and the overall look of it is a bit easier on the eyes...
There are also some new features added etc.
The only downside I see to it, is that it's not completely backwards compatible, just like office 2003 and 2007:
EAGLE 5 can open older schematics and boards, but once EAGLE 5 saves it, older versions of EAGLE can't open it anymore...
Overall I'm very pleased with it, and I think EAGLE 5 will be the new standard (for us electronics/robotics hobbyist) in no time
