My verdict: Microsoft Office 2004 for Mac is clearly superior to its PC counterpart for most users. Last fall Microsoft put out a bloated update of Office for Windows that focused more on collaborating with other users than on making it easier for you to get your own work done. The streamlined Office for Mac puts individuals first.

I spent over two years of my life on this, so it feels great to get such good feedback, and I'm proud of what we achieved with Mac Office 2004. However, I do feel the Win Office bashing is a bit unfair. The improvements in Outlook 2003 are incredible and help me get my work done more efficiently every day. And, I believe that collaboration is an area of interest to many users. In a corporate environment, you rarely work on a document by yourself. But, Win Office will hopefully steal some of our Mac Office features for their next version :-)
