One thing I found really fantastic about the OpenOffice applications is that it is readily available and downloadable from the internet and to think it offers the same features that one has to pay for in other products. You can have the word, presentation, spreadsheet, database, drawing and reviews. I can readily make charts, tables and graphs. I can easily come up with reports, memos and newsletters. I can make presentations almost instantly.
The icons and buttons you need are present in the interface. As in it's like right before your eyes. You do not need complicated keyboard character sequences. There are also built-in templates for letters and other documents. OpenOffice has a very lightweight design, requiring very low system resources for it to power up.
This is definitely a necessity for all computer users. If your office has it, then you're office document needs are all covered.
