Funny.
True story:
I was going to buy at ArchiCAD at the last firm I worked for - but the ArchiCAD reseller (being honest) told me I should also look at something called "Revit". In addition to 1) having resolved fundamental building relationships (wall/roof/floor/ceiling/levels/hosted elements...) and 2) made creating content approachable...they had also, 3) "...integrated documentation". We both considered exporting/linking for CD's to be problematic either functionally (horribly disruptive) - or philosophically (from an implementation standpoint it's horribly complex). Integrated CD's - not linking....not exporting...seemed to be a fundamental leap forward...so elegant.
So I downloaded 1.0 and have never looked back.
And the reseller? He's using Revit.
