The continued progression of OpenOffice on the Mac platform is very exciting news for those who write and work on their Macs.
If you've not read previous comments on OpenOffice, it is the open source community initiative towards developing and improving an open platform software sweet that can replace the functionality of Micro$oft Office. I had been running NeoOffice, which provides a java wrapper to OpenOffice, allowing it to run well on newer Macs, but this new release of OpenOffice is in a fully Mac native version. I was excited about this when I first got the beta some time ago. Read here for some notes about the OpenOffice 3.0 Release and for download options.
OpenOffice is an excellent choice for some solutions. For instance, we have a Mac lab in our church... no need to buy Micro$oft Office for them all... we can now deploy OpenOffice at no cost. It opens many, many file formats, including the newest Office formats, so works great in an inter-office setting. You have nothing to lose in giving it a try... it's free!
