I agree that change for change sake is frustrating, but I jumped from Office 2003 to 2010 and a year later I still hate it. It's not just a matter of it being different. It's demonstrably worse. Things that took 1 click now take 3 or more. I also went from XP to Windows 7 and I can't stand it either. Why do I need libraries and all the confusion that comes from a library location and a 'real' location?
I'm enjoying Office 2010 a lot. Especially OneNote and Outlook. Everything is so nicely done, and I'm a power-user so I'm actively using it to the limits.
But I'm a power-user and I use keyboard short-cuts, categories, search folders, write my own add-ons if I need them etc.
