I do not agree with any of the opinions provided here regarding NeoOffice.
I have used NeoOffice for eight years, as each new version came out. Today I also use OpenOffice and LibreOffice, and I can tell you from my experience that NeoOffice is in no way inferior to those other programs.
I find NeoOffice to be faster than OpenOffice.org (which has all but been discontinued in its development) and LibreOffice. NeoOffice's strength is that it is better integrated into Mac OS X than either OpenOffice.org or LibreOffice. It feels more "Mac-like" and uses Mac features, such as the system-wide spell check and Services in some cases. NeoOffice is quirky in places, but the full release version of NeoOffice is not buggy. It is quite stable. Of course if you are working with a beta version of any program, you can expect bugs. I'm using NeoOffice 3.2.1 beta right now myself.
Furthermore, the latest version in beta, 3.2.1, removes much of the deprecated code and replaces it with more up-to-date methods.
NeoOffice developers have reimplemented all of the text layout code
using the "CoreText" functions in NeoOffice 3.2 Beta.
I am upset with the tone of many comments made here. Several people who admit to never having actually used NeoOffice have condemned it as being buggy or inferior and say "Why not use something else?".
Why do other posters spread slander and gossip about a program they have no direct experience with? It would be better for you not to post at all if you admit that you don't know what you are talking about.
