Who Cares?
From what I understand Office is still the best selling piece of software for the Mac and that makes me sick.
I recently trashed my Office 04. It was dog slow compared to the rest of my apps. If Microsoft can't update their software to a Universal Binary then they definitely don't deserve my money for 2008. Yes, I understand that Adobe did the same for Photoshop, etc, but they had a lot more to convert / rewrite. Besides, it's hard to replace the entire Adobe Creative Suite. I now use either textedit, Pages, or Google Documents to open my word files and I use Google Spreadsheets to open the occasional excel file. I can't tell you when the last time I had to use a spreadsheet. There are sooooooo many other pieces of specialized math/calculating/accounting software out there, spreadsheets are obsolete. The only time I have to open an excel file is when someone creates a document in a spreadsheet because they don't know any better.
Use Keynote instead of Powerpoint and the only application you then have to replace is entourage, which I've never used.
Let's get Pages and Keynote on the Windows Platform and give MS Office a run for it's money.
