I recently switched my workstation (at the office) from a PC to a 17' MacBook Pro - great machine, love almost everything about it, except the lack of stability from Office 2004 for the Mac.
Now I know some of you will say "It's a MS product and they are the devil" but that aside, and as a "workstation" in a
work environment where 99% of documents shared and created are based on some version of MS Office the Mac seriously chugs!
I have more problems opening MS Office documents and having the entire application crash almost daily! I've resorted to opening most word docs in the office version installed on Parallels.
My rant aside, what alternatives are out there to MS Office? The only caveat to the alternatives is that they/it has to open MS Office documents

otherwise the alternative is a PC.
Any feedback is greatly appreciated.
Thanks!
