NeoOffice had a reason to exist back in the early 2000's (and even before, in the late 90's); MacOS was not UNIX based, there are nor free neither open source opposition to MS Office: NeoOffice was then one of the first introduction of Unix open source app in the mac universe. It made sense, then.
Now, the source from where Neo was forked, OpenOffice, is totaly avalaible on Mac OS. Plus, a second fork, with a powerfull community of developpers, including the original devs of the Open Office projects, LibreOffice, is also avalaible on Mac OS.
Third, the office domination is not as powerfull as before. There are lots of solutions to type, edit, design and publish text around, that fits better the web world than print-oriented old Office suite.
So, who needs NeoOffice now? And who wants to pay for it, though its siblings are free? Why devs spend their precious free time on it ? If someone can explain it to me, I appreciate.
