OpenProj is the real deal !!!!! I am using it and no longer use Microsoft Project in my company. We replaced 65 desktops with OpenProj. It works on Linux, Mac or Windows and it opens existing projects with no problem. The Projity team is amazing, Microsoft Project is 500Meg for an install. OpenProj is a complete replacement and it is 6meg. This is going to be the killer app for alternatives to Office. Project is on 8% of all desktops, why pay $1,000 and give Redmond over a $1 billion each year. This is free but more importantly better !!!! Have you every tried a WBS or RBS chart in Microsoft ? OpenProj not only has the equivalent functionality but they have interactive heirarchical charts.... this is a better solution and it is free, open source and cross platform. A nice complement to Google and Sun who are offering alternatives to Office. An interesting note: Project is part of the Office family of products but they make so much money on it without a competitor they don't bundle it into any Office suites..... that may be changing :-)

OpenProj looks pretty good. It seems to be about 80% of MS-Project (which is way more than you need considering most people only use about 10% of MS-Proj's features anyway).

Both tools are still pretty general purpose though. For software teams (one of the biggest segments of PM tool users), there are some software specific PM tools coming out. One of which is mine, Devshop (www.devshop.com). It looks at risk factors that affect software projects specifically (like: Time Estimation Error, Distraction Rates, Schedule Confidence, Requirements change, etc.), and would be instantly familiar to those that know how to use MS-Project.

Hi Zack,

I've been using it on my MacBook Pro for a few weeks and it does everything I need.
