It allows you to open and save in multiple formats besides its own .odt (open document text) with all the formatting retained.
I’ve installed OOo on my iMac 1.9 PPC machine over the weekend, just to try it out. I installed the X11 version.
It looks okay, very full featured, and I like the ability to save documents as a PDF. Documents print fine. One problem, though, is that it is very slow to open. It takes nearly 3 minutes.
Did I do something wrong during installation, or is the X11 version just slow?
Even if you don’t intend to use it full time, OpenOffice is a handy thing to have on your computer. I’ve used it several times to save Office documents that Office couldn’t open. OOo opened them just fine and the files were readable by Office after I let OOo save them using the Office file formats.
