Is there a demo you can try?
With office suites, if you like what you have don't bother switching. if you switch all the time you'll end up like me - I have a Frankenstein productivity set up:
Pages '08 - Word processor
Numbers - Spreadsheet / money
Photoshop CS3 - For Photoshopping
InDesgin CS3 - Document creation
PowerPoint (Mac '04) - Presentations for school
This "suite" cost me an embarrassing amount of money, but it is exactly what I need. Since it has no integration, I need to use some freebies to supplement it:
JView - photo viewer [way better than Preview]
Emacs - for bullying weird files open and for artifact-free text [you never think about that until you run into a problem and have to retype 54 pages
]
Quicksilver - App launcher, file opener
And this is not the perfect set up, nor is it a good set up for anyone except for me. Just try StarOffice, if you find a demo, I would be interested in trying it too.
