There is a reason that the OpenOffice.org 3.0 servers are struggling to keep up with demand. OO.org 3.0 really is a serious upgrade over version 2.4 and makes NeoOffice irrelevant for Mac OS X users (previously, OpenOffice only worked within X11; While NeoOffice did a great job porting OO.org to native OS X, OO.org 3.0 works out of the box in OS X as a native Aqua application).
Last week I asked if OpenOffice was good enough. The general consensus? OO.org is good enough to start a flame war, but we're not really sure if it's good enough to be a serious competitor to MS Office.
Now that OO.org 3.0 is out, I'm having a much tougher time seeing both sides of the issue here (I actually like Office 2007/2008, by the way; I think they're slick, well-polished, and highly functional). I had never liked the OpenOffice equation editor; this version brings a very nice graphical and text-based hybrid editor to us math teachers. Mail merge was clunky in OO.org; this version brings a mail merge wizard and improved label templates. Outline numbering tended to be a bit kludgy for notetaking in OO; this version improves the stability and interface of outlining.
I'm not actually bashing MS Office here. It's a great suite and they still have something that OpenOffice lacks: Publisher. However, Publisher was lacking on the Mac platform anyway and *nix users haven't had access to MS Office (including Publisher) without some serious Wine work. Speaking of Access, OpenOffice continues to bring a solid database offering to all platforms. Is it as powerful as Access? I don't think so (let's face it - Access 2007 rocks). However, Mac, *nix, and Windows users can all interchange databases and use OO.org Base as a front end to a variety of data sources (including MySQL).
OpenOffice.org is not a clone of Office 2007 (good call, Sun). It's a full-featured suite that gives us everything we need from MS Office and the world of productivity software while keeping the bottom line quite a bit more reasonable (you don't get any more reasonable than free).
Yes, OO.org has been good enough for a long time; the latest release should leave little doubt for any users who had been on the fence.
