Openoffice getting better and better,

A new version of OpenOffice is available for download.
There are a lot of reasons for upgrade, checkout the release notes here.
it has new artwork new glassy look which may attract most of the users.

The reason I upgraded is that being in IT sector I have to create/edit/review docs, I am always happy to use openoffice(2.4) for all the tasks except replying to review comments(MSFT).
Comments are called notes in openoffice, although you can see and edit the comments created by the junk office suite(which most of the people use) but the comments were not presented in a very nice format, a different window was opened for each note where have to put a reply. Doing this was a bit tiring and I had to make sure that the format of the note is correct. While the junk office suite provides a more fancy way of editing notes/comments every comment is presented in the margin at the right of the page.

Open office3 does the same but in a slightly better way it put the notes in the margin and also provides a scrollbar for big comments.

I use ubuntu and could not find a repository for open office 3 so I had to download the tarball and install it manually.
The installation is very easy just download the tarball and run setup. You will need rpm2cpio for the installer to work. You can chose to install the bins in a private location if you do not want to install it in a system wide location for all users.
