I have Office 2007 on my newest computer at home, which I bought primarily to familiarise myself with the Ribbon interface and allow me to discuss it from a position other than ignorance. I use Word and Excel 2007 on that computer, and find the ease of use about the same as earlier releases. Some things are easier to find and use, some things are harder.
My 9 year old daughter recently asked if she could use PowerPoint at home, as she had started to use it at her new school for making little presentations and wanted to make her own at home for fun. I put a shortcut on her desktop and let her go for it, and she has produced some pretty impressive stuff with no help from me. Not only that, but my 7 year old daughter is now doing the same thing, having learnt just by looking over my eldest daughter’s shoulder. They don’t ask me for any help, they just get on with it.
A vindication of the Ribbon’s ease-of-use claims? Not exactly. You see, they are using PowerPoint on my old computer, which has the completely Ribbonless Office 2000.
I don’t hate the Ribbon. I just don’t see much benefit in it, even for novice users.
