That's fine that you like it, but I (and many many others) disagree completely. The ribbon interface is a small step above useless.
99% of the applications, utilities and other software that I use in Windows, doesn't use the ribbon interface. So having to use everything in a productive way (like I've been doing for the past 3 decades) and then suddenly having to search through that rediculous interface for something that would of taken me seconds with any other piece of windows software (both first and third party), is a major pain in the ass. It honestly turned me from a huge MS Office advocate (I loved Office2003) to using 3rd party office solutions for friends (and went back to 03 at home)
I'm glad that some people like it, but I hear complaints about it way more often than not. If it wasn't for the fact that I'm forced to use it at work, I'd of abandoned MS Office completely.
Eh I wouldn't use the "suddenly" bit seeing how you're still considering yourself inept with 2007/2010 six years later. You only need a week or two to get used to the interface. Just as you had to get used to 95/XP/2000/2003 coming from WordPerfect and Lotus 123.
