I use open office with no issues
There used to be a time where I would use MS Word for word processing, but frankly since trying Open Office I just haven't had any reason to look back. OO has *excellent* support for .doc file formats and it also covers pretty much every feature that any casual user and indeed business user actually would need day to day. The spreadsheet and presentation software are also quite usable and I've even had reason to play with the database app which is a useful client to Postgres.
That's not to say its without fault but the major issues with addressed in 2.x and I expect further refinement in 3.0. It also has IMO some killer features such as the ability to print straight into .pdf format and presentations into .swf format. These are really, really useful features which MS Office does not have.
Seriously, if you have an older MS Office and are wondering about stumping down the money for an upgrade, just try installing Open Office. It's not going to hurt you to install it. Try opening your old files and see if they work properly, try messing around with the features you need. Maybe it won't fit your requirements, but just maybe you've just saved yourself £300 and freed yourself from Microsoft. I know I did.
