Is this the one?

The Server Side informs me of yet another UML tool release...Poseidon 3.0. But is this the one that will finally be stable, usable, and linux-friendly. The "community edition" (free one) has a lot less features crippled now, so maybe I'll download it and give it a go. I've given up on Argo, MagicDraw, Rose & others. Right now I still use xfig or powerpoint for most of my UML modelling....
