I have recently downloaded and installed Open Office for my Windows XP machine.
The installation was smooth and simple.
The only application I have tested to any extent is Writer (their answer to MS Word).
Each application includes a PDF’er. It’s output is clean and functional.
I can see no reason why the vast majority of consumers would not find full benefit and enjoyment from this office suite. I was able to create my current resume (using an old .doc Word file) and then save that into a .doc, a .pdf, and the open format .odt (among many others). It opens fast and is intuitive to use.
If using an office suite is part of your lifestyle/business there may be some very particular feature which you may innitially miss, but I would recommend taking it for a spin to see if it won’t satisfy all of your needs in this software area. It does mine.
(Ubuntu, the OS to which I am switching, comes with essentially a version of the same suite.)
