Personally I love Office 2007 and have had enough time to make the transition to the new user interface. But that is not the case for everyone. I suspect that a lot of my regular readers are starting to see Office 2007 if not on their own computers than on the computers students are using. Students hardly ever read the documentation but they are often not shy about asking others, even teachers, how to do things. Administrators are often worse about reading the documentation (can I say that since I was once an administrator?) but the expect the "computer teacher" to know it all.
Take a look. Share them with co-workers, students, friends and by all means with administrators. Why is it that administrators get the good stuff first? But I digress. 🙂 Another tool you are going to want to get is the Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats. Long name but basically it lets you open, edit and save files in the new Office 2007 formats using older versions of Office products. This update also updates the various viewers.
