Well, it looks like I'll be upgrading my office to Office 2007. Kinda forced into it. Looked into getting copies of Office 2003, but it looks like these are almost off the market, and aren't cheaper enough to tempt. Besides, The 2003 version will just buy us a little time and not fully fix the problem.
One question I haven't gotten answered is: What qualifies as an "upgrade" for buying the significantly cheaper "upgrade standard edition of Office 2007"? Most, but not all, of our machines are StarOffice 7. I was about to start upgrading them to StarOffice 8. I think SO qualified as an upgrade for a previous version of Office, but I'm not sure.
The conversion is being driven by the fact that we are getting some Excel files that SO7 does not properly handle, and internally we are trying to use some macros to control a Proposals form internally that more people are using. It pretty much requires rewriting for SO7. And, of course, there are those new file formats that might soon come our way.
So I'm also very interested in how Office 2007 will interact with our Outlook 2003 based on our SBServer 2003.
