Useful Changes
I used the Office 2007 beta since it released. For outlook 2007, I loved the new designed on the To Do list with categorised by coloured. It simplied the time for reviewing the nature of them.
As I need to send out web contents and documents in .pdf formats. The new feature in Word 2007 and Excel 2007, "pulishing for pdf" save me for both the time and budgets for my work. And the size of output file is less than either using the acrobat 7.0 or ghost script with Office 2003.
