The fact that the OmniGroup has thrown its hat into the project management ring means that Mac OS X will eventually end up with the finest project management software on any platform (won't it be nice to have a reasonable alternative to the buggy, but irreplaceable MS Project?)

It's true that there are currently project management software packages that do more, but I used those in their 1.0 version and they did less than OmniPlan. OmniPlan actually looks and behaves like a very nicely done OS X application. Plus, OmniGroup is committed to making best-of-class software applications. You'd have to have your head buried in the sand not to notice the thoroughness of their approach with OmniGraffle, OmniOutliner, and OmniWeb.

This is a beta of the second release, so if you can't handle some instability, then stick with the 1.0 version and wait until 1.1 final.
