Has anyone noticed the pleasant surprises in the Open Office 3.0 release?
It includes OO-Draw, which is a Visio-like drawing tool. I used Lanflow from Pacestar (single user license for 89$) for the purpose previously, but it's nice to have a tool within the OO-Suite. I'm keen to see if network diagrams are possible with Draw.
For those of you using OO in technical academia, OO-Math will let you write formulae, equations etc conveniently.
