I personally do not care for the ribbon UI, but many do and progress goes forward. If MS goes this way I have no problem with it. You cannot nor should you live in past accept the new and learn how to use it for your benefit. I know many people are resistant to change, you see that on numerous forums be it Vista, W7 and in the future W8.
I have office 2010 with ribbon, but I also have a add-on package that allows me to have a menu bar instead of using a ribbon, I do not use office that much any-more except for OUTLOOK so the add-on was perfect for me. If I was a daily user of Office 2007 or 2010 I would learn the ribbon.
